I have a linksys router model #WRT54G2 v1.5 and a Siemans Speedstream 4100. I am able to connect to my DSL with just my modem. If I connect everything into the router I am unable to connect to the internet. If I can connect I get a connection for about a second and then it drops. I have called Linksys and AT&T and no one seems to be able to solve the problem. I have had two people at my home looking at it and they can not figure it out either. I just got a new computer with Windows 7 and am wondering if possibly that is the problem even though everyone seems to be telling me no. Does anyone know how I can get the router to be recognized so I can use it so I can use it. The only reason I purchased it was so I could connect to the internet on my laptop when my husband is on the desktop and now it makes no sense to have it if I can't even get it to work. Not sure if there is a simple solution. I have spent about 4 hours on the phone with linksys and 2 hours with AT&T. Not to mention the time people have come over to try to get it to work. I am kinda computer illiterate so simple terms would be appreciated. Thanks.
