I've got the 76Mb FTTC service. Sometimes the web browsing is fine (although the wireless hardly ever gives speeds above 28Mbps). But a lot of the time there is a problem. I type a URL into the browser, nothing happens for 30 seconds, then a message appears saying that the web page cannot be displayed, and then a second later it is displayed. Sometimes nothing at all happens. This morning, everything was fine for a couple of hours, and now every page takes ages to load.
I get these problems with my Windows 8.1 laptop but not with my iPad. So I thought the problem is not with Plusnet but with Windows. But my son also has a Windows 8.1 laptop which works fine with the Wifi in his house but he gets the same problems as me when he comes home. So that makes it look like it might be a wifi problem in my house.
I contacted Plusnet months ago. They told me to try different wifi channels and I have been working through the channels one by one, without any improvement.
In desperation I am willing to move to another ISP, just in case it solves the problem. But before I do, I hope someone here has seen this problem before and can offer some advice.
