Sending but not receiving packets

by magwort / September 22, 2009 2:01 PM PDT

Hi all, thanks in advance for any help you can give. I know there are threads on this already but so far I haven't found anything that helped with my specific problem.

I have a 2005 Dell Inspiron Laptop with an Intel PRO/Wireless 2200BG network card. The wireless router is a Mac Airport. I have never had network connections until the past month or so.

The problem is that the internet works intermittently. I'll be using the computer and everything will be fine, and then suddenly the computer will stop receiving packets (or it will receive them VERY slowly) and the connection will slow from 54 mbps to 1 mbps, meaning of course that I can no longer use the internet.

The weird thing is, if I disable and then re-enable the wireless connection (or if I click Repair), it usually fixes the problem. The fix is only temporary, though - within a couple of minutes I have the same problem again. This is happening both on my wireless network and the one my parents have, so it's not the network. It's driving me crazy having to repair the internet connection every few minutes.

Any thoughts?

This issue has been discussed. I no longer give the long answer but here's the short one. At 4 years we disable the onboard wifi card and use anything else to fill in the task. I've used the 10 dollar WPNT511 you find at amazon for a long time. Cheaper than a trip to the repair counter.

Thanks for the advice and a follow up question

I really appreciate the advice. I went ahead and bought the WPNT511 and installed it last night. My internet now seems to be fine, however, the rest of my system has suddenly slowed down dramatically. When I look at the task manager, it says I have no processes running and only 1-2% of my CPU in use, yet I can hear the computer running, and all of my programs are now responding much more slowly than they were before. Do you know if the two are related, and if so, if there's anything I can do to fix it?

I disabled my onboard card, but have not physically removed it from the laptop (although I uninstalled the drivers). Is it possible the two cards are in some way competing with each other (like 2 different pieces of antivirus software) and that's what's slowing the system down? Sorry if that's a silly question, I have no idea how these things work.

Thanks again for the help.

My friend's v2000 Compaq did the same slow down and while it was in my care I removed the now unused internal wifi card (it is easy!) But their slow down was tracked down to an aging hard drive. It failed a hard disk test and before it totally failed we put in a new drive and cloned the old to the new drive.

Now it's faster than it was new.
