Netgear WNR3500L Wireless Router

Netgear WNR3500LRecently, my home network has managed to grow significantly. Between a couple of file servers, three client machines, and a printer, I thought my Linksys WRT350N was handling the load fine, but then it was all the other non-computing devices that are starting to eat away at the network. There are smart phones, the Playstation 3, Nintendo DS and Wii, a new Blu-ray Player that I got that has network capabilities, and the home theater receiver now too has a wired network connection. When you add up all these network devices, the typical wireless router is no longer a good fit.

Expanding The Network

The first problem I ran into is that the network must support both wireless G and N devices. Putting devices on the same radio signal causes slowdowns for N devices. Separate radio signals can be had by purchasing the latest dual radio routers, but these are usually expensive. If only some company would make an 8 port Gigabit Ethernet wireless router that would also help me out a bit, but there is not at this time a perfect router. The best solution that I could come up with is to have a main wireless N router manage the network, with a switch and another access point connected to the router. Adding the switch and access point brings up another problem. Namely that you want to maintain Gigabit Ethernet connections between the router, switch and access point. Most wireless routers and cheap switches are 100 Fast Ethernet and since the purpose of building out the home network is to deliver HD video and other multimedia services, it is best to go with Gigabit Ethernet as much as possible.

What Works?

What I ended up with right now is using the Netgear WNR3500L as my main router. This is a moderately priced router that can be had for around $70 or less. You can find the specifications on Newegg. Other than the price, the 480MHz CPU and 64MB of memory are good selling points, add open firmware support and you have a great bargain. I ended up purchasing two WNR3500L units from the local BestBuy; utilizing BestBuy’s rewardzone coupons, I was able to save 12% off the regular price.

Once at home, I went through the process of upgrading the WNR3500L to use DD-WRT instead of the default Netgear firmware. Netgear considers the WNR3500L an open router, so you can upgrade to opensource firmware packages; Netgear even has a website for you to reference: For upgrading specifically to DD-WRT reference: Upgrading to DD-WRT: Demystified first, then go to the DD-WRT Router Database to download the .chk firmware file: Netgear WNR3500L Firmware: Special File for initial flashing. You will need to flash to this firmware first in order to install a full DD-WRT firmware. Next download the actual firmware you will want to use from I went with a version of the King Mod DD-WRT that does not have miniDLNA. At this point you should be ready to start flashing, just follow the specific instructions for the WNR3500L, that DD-WRT provides.

Add A Switch & Access Point

Next comes adding the switch and access point to the network. At this time the main router does the Wireless N radio only. I hooked up my old Linksys WRT350N as a Wireless G access point. The second WNR3500L is being used only as a switch at this time. In the future I may switch the Wireless G signal to the second WNR3500L and replace the WRT350N with an actual 8 port Gigabit Ethernet switch. To turn any DD-WRT router into an access point or switch follow these instructions. The hard part is figuring out which port to plug into on the access point or switch. For the WNR3500L all ports are Gigabit Ethernet, so you can use the Uplink port, but for an older router like the WRT350N, I used one of the regular ports, since the Uplink port on that router is not Gigabit.


As usual, once it is all setup, I had some problems with my Blu-ray Player, but after a couple of resets, everything worked as designed. The Playstation 3 likes having a wired connection and it plays media files from my Windows Server now without problems. Of course having more boxes, is more complicated and the electric bill will definitely be higher after all, but the speed is well worth it and it cost me less than buying an expensive cutting edge router.

EveryDNS Setup for DD-WRT

It is possible to setup dynamic DNS with your router. DD-WRT, a free Linux-based firmware for several wireless routers, offers multiple dynamic DNS setups. In this example I have chosen to use DD-WRT with the free dynamic DNS service EveryDNS. Although DD-WRT does not specifically list EveryDNS as an option under the Setup – DDNS section, you can easily add it in the following manner:


  1. Login into the DD-WRT control panel for your router and choose Setup – DDNS.
  2. Fill in the following values:
    • DDNS Service = Custom
    • DYNDNS Server =
    • User name = your username
    • Password = password for you account
    • Host Name = your domain name
    • URL = /index.php?ver=0.1&domain=your_domain_name
  3. Save and Apply your settings.

If you are not using EveryDNS, you can find instructions for other dynamic DNS providers on the DD-WRT Wiki.

Wireless Networking Does Not Work

Linksys RouterYou ever work on something for so long that you start to think someone must be playing a joke on you, or at least laughing at you? This is the exact feeling I have when dealing with wireless networking. On the one hand, not having to run wires through your house and worrying about your dog or children tripping over them is nice, I am not sure the trade off is worth it. Let us begin with a simple home wireless network router and how the labyrinth gets complicated so easily can sometimes amaze you. Immediately you are encountered with a list of concerns that you never had with wired Ethernet, such as to secure the router or not? Any technical person would tell you that you need to secure it to prevent your neighbor’s kid from downloading all sorts of naughty things, because if you do not do this, ultimately you are legally responsible for anything that gets downloaded through your $50 router! Next you have to worry about signal interference, cause you do not want your wireless router to interfere with any cordless phone or other wireless router that your neighbor may have. Did I mention your microwave hates your router too?

Say you figured out all of that stuff and you are happy with your router security and your router’s placement. Now comes the fun part, which is having to one by one connect all your devices to your router and make them all play nice with each other. First come the desktop machines, then the laptops, and if you have mixed Windows and Macs it makes it more challenging. On older Windows XP machines, you end up cursing Microsoft for making this harder than running a marathon, and on the Apple side, you wonder if Apple documents anything at all with industry terms, it is as if Apple has to rename everything to an Apple friendly name just for the sake of being different!

If you survive all of this configuration and troubleshooting, you then are confronted with your son or daughter asking you if you can fix it so their Nintendo DS and Sony PSP can access the Internet. Oh, you probably need to fix it too so that the Playstation 3 can connect too. Overall, by this time you figured out that the easiest of all was the network printer, but for whatever reason the PS3 still can’t see your printer.

Lessons Learned

I am sure the Steve Jobs digital lifestyle works, if all you have are Apple products, but in reality wireless networking is a test of patience. What you suddenly discover is that networking is too complicated for normal people to do. With every device you add to the network, the security model tends to suffer and you see that inexpensive products like the Nintendo DS just do not support the latest security methods such as WPA2 and AES. You almost need two wireless networks, a highly secure one and a very open one that has limited functionality for all those devices that cannot connect to anything secure.
