I just bought a new Dell laptop with Windows 10 installed. I can connect to my wifi without any trouble, but I can't actively use it with multiple programs at once. For example, if I have a Putty session open and try to do something in chrome, it shows me the dinosaur page. If I wait a few seconds and refresh, chrome works, but Putty stops working - either my session dies or it freezes for a few seconds. The same thing happens with Skype and Windows Update. I don't think there's a hard limit on how many programs can use the internet, but if one program is using it another program is less likely to be successful. This even happens between two Putty windows.
This is not a problem with the network, because it doesn't happen on any other computer (including my old laptop, which was also Windows 10).
I also don't think it's a bandwidth problem with my computer's connection to the network. Downloading the initial updates and programs wasn't noticeably slow, and high quality skype video calls work fine. And the issue happens even between windows of Putty, which isn't what I would call an intense network user.
Has anyone seen this before?
I can edit in details about the computer if you let me know what's relevant.
