Sync woes

My line used to be rock steady, always sync'ing at 8128 with a BRAS of 7150.

Unfortunately a lightning strike on 4th of February wreaked havoc killing the phone service altogether and severely compromising the ADSL service. BT eventually repaired the line but it is now far less stable and resyncs at varying rates, usually less than 8128, and I get correspondingly lower BRAS rates (sync history shown below)

If I get a low sync rate is it a good idea to reboot the router, hoping that I will resync at a higher rate, or does this just make the situation worse?

Did you replace your router?

No the router is fine. At first I wasn't sure how much damage had been done and I tried my spare router, but I eventually found that only my surge protector had been damaged and the routers were ok.

Hi,

Have you already reported this to us? If so what is the ticket ref?

If not would you like to pm me the line details and I will look into this for you?

Thanks,
