I wanted to hear people's opinions on Netgear vs Linksys or DLink for that matter. Also, on the dd-wrt link I did not see a netgear product that is compatible, if that is the case would I have to rule out netgear from my list due to non compatibility with dd-wrt?
I think that each of those companies makes some good products and some bad products. There is a bit more in addition regarding the company's "character", cosmetics, etc., but these generally go out the window when you have one of their bad products. In names, I'd also add Buffalo to the list -- this name isn't as well-known, but is popular among the wireless users. But I wouldn't just compare products by brand name -- I'd get specific about the models without prejudice.
(I'm currently using exactly one of each D-Link, Linksys and Netgear products at home in my wireless network. The D-Link (DGL-4300) is the main router and wireless access point. The Linksys is of course a WRT54G (model 1) which is running a wireless bridge to another room using DD-WRT.
The Netgear is a WGPS606 -- "Wireless Print Server" which I'm not using as a print server, but as another wireless bridge. This supports client mode bridging, WPA-PSK encryption, and standard 802.11g, but not AES or WPA2 encryption. If it wasn't for the last 2 points, I'd suggest this product to you for your kids' room. But this limit is holding back my wireless security from WPA2 to WPA, and thus indicates a dated product, so I don't feel I should recommend it.
All these products, within their feature limits, are working "just fine".)
The wireless landscape is going to get somewhat simpler again once 802.11n gets cleaned up, finished, and becomes a real interoperable standard that doesn't interfere with legacy products. Unfortunately, that's not the case at present, so I cannot personally recommend draft 802.11n products. I'm not even aware of any wireless bridges that support 802.11n. At present, you'd likely buy a product that's unfinished, doesn't interoperate well, might not be upgradable to the final standard, and pollutes the airwaves and interferes with your neighbours' wireless networks.
So I'd suggest keeping it simple, inexpensive, and not pursuing the absolute best -- the absolute best for the foreseeable future is still in the committee rooms, etc., and is not yet ready and good for public consumption. Once 802.11n is finalized,
publicly tested and debugged, the scene changes and you might consider another purchase of the best. In the meanwhile, you'd have greater experience with which to judge your wants.
Products compatible with DD-WRT at this time give you the greatest flexibility. Buffalo wireless products are generally well-received and priced. Linksys is a viable option.
If you're interested in additional opinions and options, and don't get enough opinions here, you might also try other forums such as AnandTech, Ars Technica, Hard OCP, etc., etc. I'd suggest reading the existing posts first.
I really couldn't say what's best overall. I'm sure that there are tons of options which would likely work. I can only give you some opinions and wish you luck.
