Internet very slow on one computer, but not another

Question

We just had internet installed the other day. I can connect just fine via wireless with my laptop, and I have no issues with speed. Some pages will say the server isn't responding. If it does manage to get some of the page, most images will be missing, or the style sheet won't download and she gets a page of unstyled text.

I don't think it is a matter of signal strength. She has the issue both when sitting a foot from the router and when on the opposite side of the house. In both locations, the signal shows full strength, and mine works no matter where I am in the house (including right next to hers).

I've tried restarting the router and her computer with no luck.

Any ideas as to what may be the cause of this and what I can do to fix it?

Additionally: I just tried plugging it straight into the router/modem. It still loads the same page quite a bit slower on her computer plugged in than mine does over wireless.

Answer 1

Well after a very frustrating couple of days and no help whatsoever from customer service, I decided to try a different router/modem. I'm fairly certain she doesn't have any malware.

Luckily and inexplicably, a different router works just fine. It also helped speed up loading on my computer as well. I don't know if just the individual router was to blame, or the brand (Motorola).

Now everything is cruising along at blazing speeds with nary a hiccup. Thanks for all the suggestions, though!

Answer 2

Great! Good job on plugging her computer directly into the router. As it's still slow then we can rule out wireless issues. The problem is with her computer itself. You don't say which operating system you're both using, so I'm going to assume Windows.

Unfortunately, more than likely it is a bunch of Malware causing problems on her machine.

Download some anti-malware software (like AdAware Free), install it on her machine, and run a scan. If you have problems installing or running a scan, her machine might be quite badly infected.

If that's the case, try running a free online virus scan, like Trend Micro's.

If you can't even load that site on her machine, then it's probably a really bad case, unfortunately. (Many Malware and viruses are programmed to recognize attempts to remove them or access anti-malware software.)

If this is what happens, then post back here and I'll try to give you some more help.

If everything comes back clean, then great. I was wrong and it's more than likely just a lot of legitimate programs taking bandwidth. To reduce the number of programs running, press Start/Windows Menu and click on Run. Type msconfig and load that program.

In MSConfig, click on the Startup tab and unclick everything (these are a list of programs that get automatically loaded when Windows starts -- they can be started manually at any time, and so probably don't need to be loaded).

Reboot the machine and see if any of the above has helped.

If not, post back and I'll try to help you further.

Answer 3

We had the same problem.

After investigating I found out that the slower computer was on airplane mode (win 8).

Once I turned it off it started to work just fine.

Answer 4

She isn't downloading Torrents or anything is she? I'm sure if she was you;d have spotted it by now but when I am my browsing goes down the drain. Dodgy Virgin Router is to blame.

Answer 5

Without being an expert I blame the driver on her wireless dongle. It is the manufacturers' problem to create reliable and stable drivers that can connect to all routers and that is not always achieved. There isn't much to do about it, except buy one that connects through usb.

Answer 6

Had the same issue. Fixed it by going to the device manager, selected the wireless and the network devices, and in each one of them disabled "Allow the computer to turn off this device to save power".

Answer 7

looks like I'm a tad late but I think I got the answer: enter to your modem preferences (or router, I don't know the difference, sorry) and deactivate the IP overflooding option. Everything will be as smooth as grease over butter.

Hope this helps!
