Thank you for your message today and for being a part of the TPG Community.
I have attached a link with a possible fix for you to try - Good Luck
Success in the end it seems!
I tried all the fixes on the web and in the community i could find without success
Eventually after receceiving and testing three different Archer routers over a month i asked for and received a Huawei.
This has worked faultlessly yesterday and today.
So sorry to say but the Archer is may not b up to it.
