LAN network problem in conflict and now wifi but problems (Mutant HD51)

My beloved Mutant HD514K suddenly started to give problems on my LAN network, to which it is connected in DCHP and it has worked for years, in the sense that when it is connected the internet connection (1GB optical fiber) stops, works for a while then it freezes.

As soon as I disconnect the Mutant from the mains everything goes back to working perfectly.

Not knowing how to solve it, I got this wifi dongle

J&J USB Wi-Fi Adapter OEM WiFi WiFi Wireless Antenna RALINK RT5370 150Mbps mini WiFi 5370 Wireless For SKYBOX / Decoder / ZGEMMA / SUNRAY / DREAMBOX / AMIKO / FERGUSON / BWARE: Amazon.co.uk: Computers & Accessories

connected and restarted everything seemed to work but then after a few days it was no longer able to connect to the network and was unable to connect to lip.

Can you give me some advice if you can?

Thank you

The first advice is to upload a clean image, and not a backup, then test with ping to your mutant cmd: ping -t -w 10 ip-you-mutant and monitor pachet loss if there are any.

Yes Mate you are right and at he moment no problem at all with wifi
