I recently switched to Google Chrome and I keep having problems with this browser. It opens all the tabs very slowly. What do you think the problem is? Is it the browser itself or the internet connection?
Try using a different browser or reinstall the one you are currently using. If the problem persists, then it may be the network or your computer in particular. If I were you, I would get in touch with an expert on the subject here on https://howly.com/apps/issue-network/. I have used their services several times when I had big problems with my Internet connection. They were very helpful in helping me solve it.
