So I am trying to set up a router so that it connects to my computer (and the modem) downstairs, while it sends a wireless signal to my computer upstairs. If this helps, I am using SBC Yahoo! DSL as my ISP and a speedstream DSL modem. ALso for the older computer downstairs, everytime I restart, I have to click on DSL connection and login before I can even access the internet. So when I begin setting up the router downstairs, everything appears to be working (all of the necessary lights on the router are on), but I am unable to connect directly from the router to the computer. I tried pinging the router's IP address using IE, but I can't even get a login screen (where you put admin as the user name) or anything. I tried logging in through yahoo dsl anyway from PC - router - modem anyway, just to see what would happen, and I got an error 678 saying the remote computer did not respond. But at least my computer upstairs was able to get a signal from the router, which means the router is probably ok.
So just for kicks, I tried setting up my newer computer that happens to be upstairs, and tried setting it up downstairs doing the same procedure. Well, turns out most of the time I can ping the router's IP address, and messed around with the router's settings, and for a while I could get Internet access through the computer, which connects to the Linksys router, which connects to the DSL modem. woo hoo! Weird thing was I could get internet without having to log into the yahoo dsl connection program. So now I am thinking that the problem lies in the older computer. Oh and just so you know, my parents want to keep the old PC downstairs, so switching places is not really an option. But then last night, I screwed around too much with the router, and I couldnt get access through any computer. But I still have hope!
One thing about the old computer that I noticed is that it may have some sort of spyware/malware. i can't access any program through -start/programs, and I can't access my computer or control panel by going the "start" route,only way i can get into those is by getting into windows explorer. Otherwise my toolbar and icons on the desktop disappear and then reappear with nothing opening. Do you think this whole connection problem could be caused by a virus?
I am really sorry I wrote so much, but I just figured the more detailed I was, the better you could help me, and hopefully I havent confused you. If you want I could send additional info, like the ipconfig logs on the different computers.
Thank you for your time!
