The router I have is from Vegas, the router in the house is a new one. One of the first things I planned to do was switch the antenna to my 14dbi high gain directional, but the new router doesn't have a removable antenna! That's the first time I have ever seen a router without a removable antenna, and I thought perhaps I would return it for a different one. But instead I just decided to put the antenna on my computer instead, which so far is working well enough. I have a solid 2 bars signal strength, and it is reporting a 54mbps connection (though I know I'm not getting it). We also plan on reconfiguring the workspace in the house (eventually) and when that happens the router is going to be moved about 20-ish feet closer to me and only have 1 exterior wall to go through, instead of the 2 it is going through now, so that will help some.
As it is now web surfing is fine, and I have downloaded a few program updates that were mutliple megabytes that went pretty quickly, so I am probably getting the full speed of my internet connection. We aren't doing any home networking as of yet, and I'm not sure that my computer would be on that network anyways, so am not too concerened about getting the signal stronger / speed up for that purpose. Even though it is reporting a low signal strength, it has never lost it, so it is at least a reliable signal.
