For over 2 years my router (Huawei 635) has shown the following speeds upload at 20Mb/s and download at 74mb/s.
Last week the interenet kept dropping often after just 10 mins. Openreach apparently found an issue and corrected it and last weekend the internet was up for 4 days. However the speeds had dropped to 16mb/s upload and 66mb/s down load.
Then 2 days ago the internet started dropping again, since this morning the internet has been up but the router now show the following speeds 15mb/s upload and 60mb/s download.
Why have I lost nearly 20% of my broadband speed and will it recover?
