One other thing i might try if you have not already done so; is on the pc that is having the issue; go into the device manager in the control panel and completely uninstall the network adapter(s) for that pc. Then reboot; let windows re-detect and reinstall and and all adapters and then update them to the latest drivers if there is any updates. Try this if you have not already done so and see if it does anything for ya.
Thats what I just did so going to see if it helps. Already though I was told to check my network connection when downloading something even though I was clearly connected to the internet. I had to restart the download but has been fine so far. Any other diagnostics I can run on the wifi?
Alright I finally fixed it.
Wait till you read this crap!
After bickering with comcast (my internet service provider) they turned on bridge mode or something on my combo device. (basically it turned my modem/router combo into a modem with the router capabilities turned off) I hooked up my own damn router and boom...everything is working properly...but besides that the modem router combo was only in g/n mode and I switched it to b/g/n mode. Which I never got to test and see if that helped.
But anyhoo it's finally working wifi is perfect everything is perfect! Thank you so much everyone for dealing with me and trying to help me with this problem. I'm very appreciative and so happy things are finally working!
