If you are in the market for a new home router, you should review the following list. First of all, the routers have passed a series of tests and are logo'd as "Works with Windows Vista." To get that logo, they must also pass the Xbox Live compatible tests. As you you can see in the list at http://winqual.microsoft.com/HCL/ProductList.aspx?m=v&g=d&cid=712&f=86b, they are all wireless routers.
Why would I care? I was trying to solve a problem. I could not communicate with my friends via the voice communications possible with Xbox Live games. I'm not really sure when that broke, but it became really apparent over the Christmas holiday. Since I knew I was moving from the static business plan to the residential dynamic plan, I deferred looking into it. Once I moved, I started using the originally issued router (D-Link) from Verizon because the Actiontec wasn't compatible with my ATT CallVantage VoIP. But Xbox Live voice comm still wasn't working.
I needed a wired only router. My wired GigE backbone is wirelessly bridged using some small compact wireless bridges from Buffalo Tech. They don't even make them anymore. I guess there isn't a big market. Oh well. http://winqual.microsoft.com/HCL/ProductList.aspx?m=v&cid=710&g=d shows the wired only routers that have passed the logo testing. So I ordered the D-Link EBR-2310 from newegg.com and so far, it is working flawlessly.
Xbox Live comm is fixed. VoIP works. The fiber speed is good. Sustained downloads don't bomb out. So far, so good. If I hit any issues, I'll let you know but it's nice when $30 plus shipping solves a problem.
