WiFi Slow and DNS errors

[Staffordgooner]

Last couple of days WiFi has slowed down from 50Mb to as low as 1MB. Impossible to run Teams calls. H/W S/W is FAST5364 3.00 / SG4K100136

mulitple DNS server connection errors in the log file. 

Broadband is running at 50Mb with no drop outs

Firmware was upgraded today after factory reset. 

Problem still there. 

Please help?!?

Hi Michelle,

"Edited"

I realise I would need to buy an adaptor for my laptop. I can do this, but it will take 24 hours for delivery.

Morning,

I've run a test on the line now which hasn't detected a fault and the sync speed looks consistent. Would it be possible to test wired the next time this happens so we can confirm if this is solely related to the wireless please as we can then offer more assistance.

Thanks

Just realised DNS may be red herring as both devices were probably in standby mode at that time. 

So, symptom is falling WIFI speeds, well crashing actually to unusable slowness.
