R8000 Slow download speed on wired and wireless connections

[jpmoynihan]

I'm connecting via a BT supplied modem to BT Infinity. I'm seeing 80M coming out of the modem but about 15M wired and wireless out of the router . There used to be no drop off in speed. I'm on the latest firmware - what to do next ?

I unchecked QoS and rebooted the router . Speed out ofthe router and round the house returned to high 70s

Hi jpmoynihan,

Have you tried to reset the router to factory default?

If resetting did not work try lowering down the MTU size.

Hi jpmoynihan,

Good to know it is working now.
