Web-search the computer model for potential problems with the laptop.
Guessing it doesn't have an Ethernet plug. If not try using it.
Hope its a software issue. Hardware you're screwed.
Updating drivers may not be enough.

Try these: (just beware if you uninstall wifi driver you wont connect to internet. download driver install before) http://www.tomshardware.com/answers/id-2397826/laptop-slow-wifi-internet-access-fast-problem.html

Thanks. Trying your links.

If you read again, the Ethernet is pretty fast, actually.

also make sure that windows has 802.11n enabled in the WiFi options

Boot from a Linux Live CD/DVD/USB and see if the speeds are any better. Try something light but user-friendly like Lubuntu or Peppermint OS. If the speeds are better it's a software issue. If speeds are the same it's a hardware issue. Be sure to test both adapters. You may need to change some settings in the BIOS to get it to boot from the USB drive, but it's usually not difficult to do so.

I see the utility of this, but I don't think it's going to happen. Thanks, and sorry to be a Debbie Downer. It's my old lady's machine and test booting is not worth the fit she'll pitch because she doesn't understand.

You do realize with a Live CD/DVD/USB that you aren't installing anything, right? It runs from the disk or USB drive.

At any rate, have you tried speed testing on another network? Take it to your local McD or coffee shop and see if speeds are better on a different network. If they are faster there then there may be a problem with the router.

Thanks. The USB is Edimax ac1200 and the router is Zoom 5354. I'm not seeing incompatibility. I turned off IPv6 and reconnected. No great fixes there, but I'm updating the driver (slow, given the connection) and preparing to reboot.

Will try the WiFi Analyzer, but none of the other devices have a problem.

Does she have any file sharing software running (bit torrent, limewire)?

I would run msconfig and do a selective startup and disable all non-Msft services. See if your throughput increases then

Check to make sure Power Settings aren't set to limit the WiFi card.

We're good here. Still at 2MB/s

After searching for issues regarding the router/adapter you are using I stumbled on to this review from amazon. Due to the review's age I'm not sure how relevant it is to your issue, but it does sound like a similar situation.

It sounds like the software for Wifi is pooched.

I had an IP6 problem on my work machine but it was the same wired and wireless. Mac Pro.

Another idea could be is that Wifi card isn't sitting properly. Or the antenna connection is bad.

Two bad antennae? Doubtful.

There are two cards: internal and USB. Both sitting bad? Both have bad antennae? Doubtful.

I think the pooched software is a better bet. I'm rebooting (after following advice above). The router is 802.11n... still trying.

Well .. Yeah ... The USB shouldn't have a problem. But you didn't say your hardware and we are all a guessing here.

The best bet is a complete wipe and reinstall of the OS.

The router isn't the issue since you got the LAN pumping fast.

Buy an external wifi card. They are like 20 bucks on amazon. That is the solution if you can't fix it through software and from what you say it sounds like a bad wireless card in your laptop.
