I upgraded my old Linksys router after it went out to lunch last year. It was hanging and causing problems for a few months before that and I would have to reset it almost daily. I ended up going with a Apple AirPort Extreme
router that I found on eBay for $99. The place I bought it from had a bunch of them they got as returns that were still in the retail packaging.
The normal price on AirPort Extreme router is $179, so for $99 I thought it was a good deal. You may be able to find the same thing on eBay now or you can look at http://store.apple.com/us/browse/home/spec...mac_accessories
and get it refurbished for either $129 or $149. I am not sure if there is anything different between the 2008 and 2011 model they have there. All Apple refurbished products come with a 1-year warranty just like the retail products.
I have been happy with my AirPort Extreme and I get a little further wireless range now. You set it up via the AirPort Utility for the Mac or Windows instead of using a web browser to administer it. At first I didn't know if I liked using software instead of a web pages for administration coming from the Linksys router, but now it is nice to have a easy to use interface.
I actually just bought an Apple AirPort Express
a week or two ago refurbished from Apple to extend my wireless network and be able to have a wired network jack up in our dining room where I am building my new computer. I also work on other desktop computers without wireless cards in the dining room from time-to-time for people, since I don't have room by my computer desk in the family room to work on them.
You can use the AirPort Express as a wireless router and it is only $69 refurbished or $99 new. If you use it as router it can only be used for 10 wireless connections, since it limits you to 10 and only has one ethernet port on it where the cable modem connects to it. I am still using my AirPort Extreme for my main router that my cable modem connects to and my desktop computer, then I am using this to extend my wireless network and give me a better signal out on the patio for when it gets warm again and the snow goes away here in Cleveland.
When I got the AirPort Express last week it was working, but I didn't like how I configured it at first to connect to my 5GHz network and I couldn't connect to it with my laptop. I tried resetting it to factory defaults by pressing in the reset button while plugging it in and then it died. I kept getting a solid amber light and then it would flash green for a second and go back to the solid amber light. I took it to our local Apple Store to the Genius Bar and they couldn't get it working either. The guy went in the back to find a replacement, but he couldn't find one, so he gave me a new retail one instead. This meant that I paid $69 for the retail version that normally cost $99. SWEET! It is working now and I am actually typing this on my new Hackintosh desktop computer using the AirPort Extreme to connect to my wireless network and the Internet.
The one other thing that the AirPort Extreme has to offer that some routers don't have is the dual band antennas. This allows me to have two separate networks running. I can have a standard wireless network and a 5GHz network running at the same time. Some of the new routers also offer the option to have a guest network that your friends and family can use when they stop over if you don't want them on your main network.
I am happy with my AirPort Extreme and AirPort Express set up. I don't know if the Internet is any faster, but at least it is more reliable now. The Airport Utility for managing the routers is also nice and keeps things somewhat simple. I think you would be happy with any newer Wireless-N router and if you get one with dual band antennas that will give you more options too. I was happy for a long time with my Linksys router and I can't say anything bad about them, but I decided to go with the Apple router, since $99 was a good deal for what it had to offer at the time. My brother would call me a sell out for buying an Apple product, but I am happy with it and don't have any complaints.
