TG, the dell is hardwired into the router, so no problems with it. Yes mac is current with all updates.
12 - I have tried sitting next to the router (did that while on the phone with linksys) and the connection was intermittent no matter the distance. also having the same problem with my iphone so I dont think the problem is the wireless card.
right now I am as far away from the router as I can be while still being in the house and have had a full signal for at least an hour....sometimes it is great, then it will drop for no reason I can figure...and after several hours on the phone with linksys I'm not sure the manuals they give the reps in the Phillipines are all that accurate.
I went to apples website and there are a bunch of threads on the discussion board there about a safari update that seems to be causing this issue with a lot of people (going back to 2008) and after replacing routers, wireless cards etc. people were still having a problem...the last comment on most of the threads I found were about six months ago which makes me think the problem was resolved but I cant find the fix anywhere.
Just a vicious circle....call the ISP and they blame it on the router, call linksys and they blame it on the computer, call mac and they want $100 to talk to you.
I have talked with people in India twice, the Phillipines 3x...it cost too much to talk with someone in english that can help fix the problem...#6 is heading to the top of the list as far as solutions!!!!!
