wireless internet being interfered with by ac power

by jeffhodgin1986 / September 7, 2008 12:30 PM PDT

i have a laptop and when it is plugged in (a/c power) the internet goes very slowly through my wireless connection. the connection to the router is still perfect the internet just moves very slow. As soon as i unplug my laptop from the wall the internet moves much faster. There are no settings or programs that change when i plug and unplug my computer. I am baffled and normally pretty good at solving my own problems. Any ideas?

Use system restore to when it worked proper.

There is not one good clue in your post. While I could take shots at it, I hope you could supply at least what the forum note asks for next time.

using xp service pack 3, working on a Broadcom 802.11b/g card, and working on a compaq presario V200. Sorry thought maybe it was a general problem not something computer specific.

In reply to: information

Now that I can share something about this. My neighbor owns a V2000 with the Centrino and similar to what you listed. The issue is now well known but you will find people that will not want to accept it. I'll not repeat the entire story but share how we fixed it.

We pressed the button to turn off the internal wifi card. We found the WPNT511 card on for 20 bucks (now 15 at ) and installed that. If you want our opinion, use XP's Wireless Zero Configuration or WZC.

While we waited for the card he just ran "wired."

Thanks for the final detail. Hope you don't lose as much time as others have on this one.

PS. Yes, you can research getting a new wifi card. Yes some have done that. Yes, it's been discussed but I'm a bit tired of trying to tell people not to waste their time. Yup, your choice here.

In reply to: but why

The issue is now widespread. I've written about it too many times but it's a known issue and failure. If you really really must, replace the internal wifi card. It usually just fails later again. REMEMBER you can't use "any" card. Again, a long explanation would be needed as to why but the short answer is "it's locked to that card."

The machine is well out of warranty so count yourself lucky if you escape with a 15 buck fix.
