Intermittent wifi drop out - "Defragmentation failed"

Getting regular (up to 5-6 x day) drop outs on Wifi.  I've checked the connection status and the route tells me it's connected OK to the Plusnet network though.

The Event log shows mention of "packets being blocked" and "defragmentation failed"  I've listed them below for info.

Any ideas?

2.4ghz channel is set to 6 as advised

5ghz channel left on auto as advised

Thanks!

Re: Intermittent wifi drop out - "Defragmentation failed"

@rdl1972  The BLOCK events are the router firewall stopping attempts to access the router from the internet and are quite normal.

Your troubles are more likely due to the various wi-fi problems that the Hub one exhibits. Have a look in the router section of the forum. The link below is the massive thread about 5Ghz problems for which some test firmwares have been sent out if you ask.

https://community.plus.net/t5/My-Router/Hub-One-5GHz-WiFi-issue/td-p/1696363 

There are other faults relating to reduced speed on 5GHz and some DNS problem which are known and will be fixed in a future firmware release, when that might be who knows.🙄

I have never used ISP supplied equipment and the endless problems with the Hub 1 which is actually a rehash of the old BT hub 5A justifies my decision. However the BT Hub 6 is much better, many Plusnet customers use one.

Re: Intermittent wifi drop out - "Defragmentation failed"

Thanks for your help @RealAleMadrid 

I'm having no luck with the router at all so am going to try just using it as a modem and running the wifi through a couple of Google Nest routers. 

I've checked out the posts from people who have managed to do this with a Plusnet One so fingers crossed I won't lose what hair I have left setting it up Smiley
