Random internet dropouts.

[bytes]

For the last few weeks I have random BB dropouts. They normally  only last a few minutes and can be several times  in an hour, annoying when streaming and playing games.

During dropout wifi signal is good and says " connected without internet".

I have contacted talktalk help via chat 4 times now and all they do is test line, change channel and reset router.

Anyone here suggest what to do next to fix this.

Thanks

Which make/model of router are you using? When this happens, what is the exact status of the light(s) on the front of the router? Are wired (Ethernet) connected devices affected as well, if you have any?
