I've been having this problem with my wireless connection in my house. I have a Linksys WRT54Gv5 wireless router that works. It is currently downstairs where I am located. I have my desktop computer plugged in wired, along with my Wii and PS3, though the only connection thats actually on all the time (for the most part) is my computer. My PSP, DS, and Laptop all connect wirelessly without much trouble.
The problem is my mothers computer which is upstairs above my room (and a little bit farther). Most of the time her computer (now my old computer) can't connect to the wireless. My house is rather long, and the only reason that her computer can connect is because I bought a wireless Range Adapter (one of the ones by linksys, bounces the signal strength or something). It see's the network but it can't connect to it, always says limited or not connectivity. Sometimes i'll get lucky and it connects with either a low connection or "very good", but it bugs out a lot.
Lately its just been getting on my nerves and im near the end of my rope trying to figure this out. For example now it won't connect at all. The signal strength fluctuates anywhere from 60%-85% but no matter what it just won't connect. Always gets limited connectivity. I did change some wireless options online in my routers menu, but I changed them back to the origional when I was done. I can't figure out what the problem is besides range, but like I said, sometimes it works with very good, but a lot of times its limited.
What should I do? Is the linksys router bogus? It notice that it sometimes drops my wireless from time to time, and when im in my room (which is downstairs almost below my mothers) my connection will be fine, drop, then I have to walk near my router in the other room to reconnect.
Please, I really could use some help. Anything. Should I get a new wirless router? If so what? Is it a problem with something in the wireless admin menu? Channel?
Thank you all very much for your help.
