iPod Touch Review: Belkin Silicone Skin Case

March 6th, 2008 No comments


Belkin Silicone CaseI’m always looking for decent cases for the devices I carry, and I have found another case for the iPod Touch that I just love. The Belkin Silicone Skin Case is a molded case made of silicone rubber that stretches to fit snugly around the iPod Touch. It provides cut-outs for the screen, top power button, brightness sensor, Universal Connector, and headphones. There is also a recessed portion over the front Home button giving it a great look and nice tactile feel. The case nicely protects the chrome back from scratches, and it provides the iPod Touch with a great grip. It only adds just a fraction of an inch to the overall size, so your iPod Touch remains slim and sleek.

This case is simple, yet elegant in design, but like similar “skin” cases it does not provide any protection for the screen, so a modest screen protector is included. (I personally use some left-over Palm PDA screen protectors, though the supplied protector will work just fine.) This setup makes the iPodtTouch very “front-pocketeble”, and I am much more likely to regularly carry it with me because of the small size and confidence in the protection. After all, what’s the point of having a device that contains your favorite content if it is too bulky to take with you? Currently, this is my case of choice.


ReplayTV Tip #7: UPDATE: Belkin F5D7230-4 Router

July 26th, 2004 No comments


I purchased a used HP EN5000 Digital Media Receiver off of eBay. The EN5000 is a "Media Receiver" that lets me play (through my stereo and TV) MP3 files loacated on local network servers. It's not the most feature-rich device, but for a low eBay proce of $27.00…. Anyway, it requires an Ethernet connection, so I decided that an additional Belkin F5D7230-4 Router would be the most economical connectivity solution.

In a prior article found here, I discussed how I set up my wireless network by leveraging the high configurability of the absurdly inexpensive Belkin F5D7230-4 Routers. I described how I configured three of these suckers to provide full-house coverage for all my networking needs. Read on to see what I did to improve my home network…

I purchased a fourth Belkin F5D7230-4 router to provide additional connectivity in another room. The wireless coverage was absolutely fine, but I didn't have any Ethernet jacks in the room, so adding the additional F5D7230-4 would provide the needed ports while seamlessly fitting in with the wireless network (more on "seemless" later.) One thing I am REALLY liking about the F5D7230-4 is that because it has 4 switched ports, it's basically like adding a wireless "hub" in the room. Wired Ethernet devices that connect via the switched ports simply see a 100MB Ethernet connection on the network. The reality of course is that the overall throughput is at 54MB 802.11G speeds, not the full 100MB, but for my devices, this is perfectly acceptable. In fact, after surveying everything I have connected, it turns out that the only "real" wireless device in my house other than the F5D7230-4 routers is a laptop. All other devices are standard 10/100 Ethernet, so I just use the F5D7230-4's to provide the ports to 54MB wireless connectivity instead of stringing wires everywhere.

ADDITIONAL TWEAKS:
After living with my wireless network as described in my other article, I decided to alter some of the settings to help improve performance and to secure the network. Here are the changes I made:

1. Configure Routers as "Access Point Only":
With the exception of the F5D7230-4 that's connected to the Cable Modem (I left that configured as a Router), I configured all routers as "Access Point Only". This way, they are only set to "do one thing". My idea is to simplify the settings and reduce the number of factors I have to handle during troubleshooting. Further, I only have one of the routers set to "allow client connections". This means that router is the only one that will accept connection from other wireless devices (ie: my laptop.) All the routers still act as wireless bridges, so basically this means that the routers are really nothing more than WEP-secured, wirelessly-connected, 4-port switched hubs, one of which allows for WEP-secured 802.11G connections. The end result is actually pretty slick.

2. Setting the IP Address:
By default, when you configure the F5D7230-4 as an Access Point only device, the configuration page defaults the Access Point to a new IP of "192.168.2.254". Obviously, I couldn't have three of the routers configured to the same IP, so I just changed the defaulted IP to an IP address that made more sense. In my situation, I have the F5D7230-4's configured with IP's ranging from 192.168.2.1 to 192.168.2.4–makes troubleshooting a bit easier. 192.168.2.1 is the router connected to the Cable Modem, and it also is the address used as the "Gateway" and "DNS" for any connected devices.

3. Configure Wireless Bridging:
Next, I configured wireless bridging as needed. I won't detail the specifics, but as an example, I configured wireless bridging on the router to which my ReplayTV box is connected, to bridge directly and exclusivly to the router where my "Video PC" is connected. That router, in turn, is configured to wirelessly bridge to the router that connects to the Cable Modem, and ultimately to the Internet. So, when my ReplayTV box does a "net connect", it finds the Internet and does a "moderate-speed" connection, hopping across a couple wireless routers. This is not a high-bandwidth transfer, so speed really isn't important. On the other hand, when I want to stream or transfer video between the ReplayTV box and my PC, it has high-bandwidth requirements, so it only has to go between one router-to-router wireless connection.

4. Security:
I next enabled WEP on all wireless devices. My network is now more secure. The nice thing is that WEP only concerns the wireless connections, so it's completely transparant to devices connected via the switched ports.

5. Labeled everything:
I used my wife's P-Touch labeler to create IP labels for any device that uses an IP address in the house. This way, I don't have to remember what is what, I just look at the label. They can be applied in inconspicuous places, and for those that aren't, they give the devices a nice "geek-look"!

Now to address that "seamless" comment above. OK, I have to confess one thing: It took me almost TWO HOURS to get that fourth F5D7230-4 configured and "talking" to the rest of the network! Once again, one of those "5-minute projects" escallated into a very frustrating evening. It turns out that I simply mistook the "WAN" MAC address stamped on the bottom of device for its "WLAN" MAC address which is only discovered through the Configuration Home page. Once I inserted the proper "WLAN" MAC address into the bridging tables (initially, I was using the "WAN" MAC address), things "lit up" properly and I was good to go. So the tip is this: The "WLAN" MAC address is ONLY viewable in the configuration page, NOT on the device itself. It can't hurt to just label everything or at least write everything down for later reference.

CONCLUSION:
I have four WEP-secured wireless routers scattered around my house; all sharing a channel that's not being used by other Access Points in my area; all visible to each other; all routed to the Cable Modem. As my needs grow, it'll be a simple matter of just purchasing another F5D7230-4 and configuring it into the mix.

So now, my wife and I can finally relax and listen to music in the comfort of our living room as it was meant, instead of huddling around the PC!

ReplayTV Tip #6-Multiple Belkin F5D7230-4 Setup HOWTO

June 22nd, 2004 No comments


After purchasing a new house, I needed to set up a network. An 802.11g wireless solution seemed to be the best choice, so after lots of research and planning, I purchased three Belkin F5D7230-4 routers and configured them to provide wireless routing, bridging, and access. Read on for what I did, how I did it, and how it has worked…

Multiple Belkin F5D7230-4 Router/Bridge/AP Setup HOWTO:

A Guide to Setting Up Multiple Belkin F5D7230-4 Router/Bridge/AP’s

By Jim Barr

Introduction

BACKGROUND:
My wife and I were fortunate enough to purchase a new-construction house. Unfortunatly, we purchased it just after all the walls were installed, so I was unable to have network cabling installed throughout the house. Bummer! The house certainly has ample attic and crawl space, but the notion of later installing whole-house wiring, though doable, was not too appealing. I tried installing an 802.11b network using some old Linksys equipment I had, but the throughput was simply too slow to stream ReplayTV shows, and for some reason, it wasn’t that stable. Also, thhough I’m in a relativly low traffic area, there are two other 802.11b accesspoints within range of the house, so I decided to go with an 802.11g network. The challenge was to determine how just what equipment I needed.

After pouring over countless posts on the AVS Forum, I decided to purchase three Belkin F5D7230-4 routers. There are many other router solutions on the market, and some offer higher speeds, but the one important feature of the Belkin F5D7230-4 router is that it can be configured as any combination of router, wireless access point, and wireless bridge. As of this writing, most comparable routers either don’t offer the same flexibility or they are priced much higher.

PURCHASING:
Initially, I decided to purchase three Belkin F5D7230-4 routers from CDW because my wife’s company gets an employee discount through them. I figured that $56.00 each was a fair price, so I ordered three. Their site, as well as an account manager, said that they were in stock and would be shipping in 1-2 business days. After about a week of my order status simply saying "Processing", I called them and they said that the Belkin F5D7230-4′s were backordered and would arrive in about a week or two. Needless to say, I wasn’t happy, so I canceled my order with them and placed an order with J&R Music and Computers (www.jr.com) The routers arrived just 4 days later, and they cost under $50 each (and I’ll even be getting a $20 rebate on one–very nice!) I have ordered several products from J&R, and I highly recommend them. They haven’t let me down yet. (CDW, however, is another story–at least they are consistent in their poor service.) OK, OK, this isn’t a "consumer report", so on to the good stuff…

BASIC SETUP:
Setup wasn’t as tough as I expected, but there are some idiosyncracies to work through, so patience is required. Within about an hour, I had everything in place and working wonderfully. Here is a simple block diagram of my setup:

[ISP] <-Coax Cable-> [Cable Modem] <-Patch Cable-> [Router 1] <-WiFi-> [Router 2] <-WiFi-> [Router 3]

DETAILS:

[Router 1]
-IP: Static 192.168.2.1
-DHCP Server: Enabled, range 192.168.2.101 – 192.168.2.120
-Configured as router and bridge
-Set up to bridge, accepting MAC address of [Router 2] only
-Set up WLAN as "56G-Only" and NOT allow Wireless Client access
-Set SSID to NOT broadcast -My wife’s Work VPN PC is connected via cable on a LAN port and gets its IP via DHCP from [router 1]

[Router 2]
-IP: Static 192.168.2.2
-DHCP Server: Disabled
-Set up as bridge only, accepting MAC addresses of [Router 1] and [Router 3] only
-Set up WLAN as "56G-Only" and NOT allow Wireless Client access
-Set SSID to NOT broadcast -My home office PC is connected via cable on a LAN port and gets its IP via DHCP from [router 1]
-My video editing PC is connected via cable on a LAN port and gets its IP via DHCP from [router 1]

[Router 3]
-IP: Static 192.168.2.3
-DHCP Server: Disabled
-Set up as bridge only, accepting MAC addresses of [Router 2] only
-Set up WLAN as "56G-Only" and allows Wireless Client access
-Set SSID to NOT broadcast -My ReplayTV 5040 is connected via cable to a LAN port and gets its IP via DHCP from [router 1]
-My 801.11g laptop connectes via WiFi and gets its IP via DHCP from [router 1]

All routers have the following in common:
-Version on box: 1444
-Firmware version: 4.x
-SSID is set to the same on all routers
-SSID Broadcast is turned OFF on all routers
-Channel was set to a channel not being used in my neighborhood
-I do not have WEP enabled yet, but I will in the near future.

THE SETUP PROCESS:
First off, I used my laptop to configure each F5D7230-4. I connected it with a cable through the F5D7230-4′s LAN port eliminating any need for wireless configuration on the laptop. This significantly simplified the setup. Because the F5D7230-4′s are so portable, if you don’t have a laptop, just use any PC and a network cable.

Setup of the first F5D7230-4 consisted of running the included setup disk on [router 1]. As mentioned above, I connected my Laptop through the LAN port, and the setup was a simple, 2-3 minute process. The end result was that I could connect my laptop to the Internet as well as connect to the Web-based configuration screen on [router 1]. I logged into the Web Configuration screen and set up the IP address, DHCP Server, and WLAN settings. (Note that when you change the IP address, you have to re-connect to the Web Configuration screen with the new IP address. I then enabled bridging and entered the MAC address of [router 2].

Next, I powered down my laptop and disconnected it from [router 1], connected it to [router 2] via cable to the LAN port, and powered on [router 2] and then my laptop. Note that [router 2] was NOT connected to anything else other than my laptop. Specifically, the WAN port was NOT connected. I then opened the Web Configuration screen on [router 2] and set the up the IP address, disabled the DHCP Server, and set the WLAN settings. I enabled bridging and entered the MAC addresses of [router 1] and [router 3] and I disabled wireless client access. I then rebooted [router 2] and the laptop. The end result was I was able to connect to the Internet through [router 2] and access the Web Configuration screens for both [router 1] and [router 2]. OK, I know it’s "just technology", but I have to admit that I found it very cool accessing the Internet connection and seeing no wires connecting the routers!

Setting up [router 3] was basically the same as setting up [router 2] with the exception of setting a unique IP address. Once set up, I rebooted everything for good measure, and was able to connect to the Internet through all three routers.

The only idiosyncracy to be aware of is that DHCP Server is enabled by default on the F5D7230-4, so there may be initial conflicts until you can disable the DHCP Server on all except one router (or wherever you want it set up, if at all.)

FULL SYSTEM RESTART:
At some point, I know I’ll have to do a complete "system" restart. This could be due to a power failure, a system glitch, or something entirely different. A full system restart would consist of: Power everything down. Power up in order, the cable modem, wait for it to sync. Completely power up [router 1]. I can then power up any device that directly connects to [router 1], specifically, my wife’s PC and [router 2]. Once [router 2] is completely powered up, I can then power up any device that directly connects to it, specifically, our home office PC and [router 3]. Once [router 3] is completely powered up, I can then power up any device that connects to [router 3], specifically, my video editing PC (and eventually, my ReplayTV.) If you think about it, the order really makes sense–you just have to look at things logically and understand the dependencies.

(Edit: I noticed after a month or so of use that powering on or off just about ANY device in ANY order "just works". The only exception is that [router 1] has to be on before anything else because it’s my DHCP server. Otherwise, it’s a very simple network to maintain.)

CONCLUSION:
So, what does this give me? Devices connected to LAN ports on each router can access any other device connected to any other LAN port on any other router including the Internet. 802.11g devices can connect via [router 3] and can access any other device on the network including the Internet. 802.11b devices can NOT connect to the network. I did this purposly to help reduce conflicts with neighboring 802.11b access points, to improve my network throughput, and to simplify the overall setup.

Note that I could set up wireless client access to go through [router 1] instead of [router 3] eliminating two hops, but due to the physical location of the routers, [router 3] gives me the best connectivity. Surprisingly, throughput, especially to the Internet, is excellent.

After working with this setup for about a month, I simply couldn’t be happier. Wireless access throughout my house with my laptop is very good, and throughput on all devices is excellent. Devices like my PC and the ReplayTV box simply "think" they are connected to a wired LAN (technically, they are) so there’s no special setups. Further, because I have my two PC’s connected to the same F5D7230-4, the F5D7230-4 is effectivly a 100MB switch which gives me high-speed throughput between the two PC’s.

The F5D7230-4 so far has proven to be an all-in-one workhorse that once configured, just works and works well. The design is excellent, and the configuration is pretty intuitive. Network novices may have some difficulty, but only because they may not be familiar with "routing" and "bridging" concepts. If you have any networking experience, it’s a snap. My only real recommendation is that you spend some time thinking through exactly what you are trying to accomplish before you start configuring. Overall, I highly recommend the F5D7230-4 and J & R Music and Computers as a source.

THANKS:
Thanks to those who assisted me with this setup. For once, a simple project in theory turned out to actually be a simple project in reality! That certainly is not typical! I want to thank "sfhub", "SpaceCadet", and "GooberedUp" on the ReplayTV Forum on the AVS Forum site in this thread for their excellent help.
