Windows 10: Downloading crashes the internet

This problem hasn't happened at all before in the past. However, for months, downloading or updating games on my pc will end up crashing the wi-fi for the entire house.At first it downloads normally for a couple minutes while slowly increasing in speed until it hits about 33/mbs where it will plateu and then crash after some time. It takes about three minutes for it to reboot itself and everything to go back to normal. One thing I haven't tried testing was to see if it was only my pc that was crashing the wi-fi after downloading. I have tried calling my internet service provider multiple ti

:)

 

all games crash!

I suggest you run rthdribl > http://www.daionet.gr.jp/~masa/archives/rthdribl_1_2.zip
Increase the window size step by step and watch your vga temps permanently.
What happens?
If it crashes, run at stock speeds as suggested before and retry.

P.S.: When your system locks, does the display signal turn off after a time?
Stuttering sound or no sound at all when freezing?
What X1800XT model do you own exactly?

 

Internet Crashes Constantly when uploading/downloading

So whenever I tried to upload a video or download like music or something my Internet crashes. I am connected through wifi, and other times i'm connected with Ethernet which doesn't crash my INTERNET. I like the wifi better though because it's faster I really want to fix this problem someone please help.

 

Internet Downloads

Thanks all for the useful suggestions, i certainly can understand the idea of refreshing downloads. I wish Firefox had that little button lol. Now i'll try and download Warrock (a great FREE game) with download manager though (annoyingly) firefox is now downloading without buggering up!
I just did a few spyware scans which though didn't stop the probs it probably did stop all thoses bloody programs from using the internet and slowing it down.
