Well my 5 Pro had network connection problems form new but after only 3 weeks it became impossible to use it, my 7yr old Dell laptop and desktop on the same router working without any problems.
Having taken out a Premier Care support package, next working day home repair, I thought that at least it will be sorted quickly.
It took 3 weeks for them to fit a replacement WiFi card and it still has the same problem. Incidentally, the engineers work for IBM a Lenovo subsidiary and they are not allowed to enter your property so any parts require have to be sent to you they then come and pick up part and laptop and return it the same/next day. However, in my case they took 3 weeks to organise that so much for the next working day service.
However, I am left with a laptop I can't use as the Wi Fi connection keeps dropping out. Premier Care are now just offering to take my laptop away for 7/10days, so much for next working day home service. Had just 3 weeks sporadic use with network constantly dropping out and now another 4 with Premiere Care clearly unable to resolve the problem.
Has anybody else had this problem or knows what the cause is?
It would appear too not be an isolated incident as I found this on another site:
My legion 5 pro purchase has gone from bad to worse. Wifi stopped working after a month. Premium support changed the WiFi card , no luck. Eveb after changing the Motherboard, the WiFi was not working. I had to send the laptop to their depot and again they have ordered for WiFi adapter. It is still in their depot. Nightmare.
hopefully it's a small minority of laptops with this issue... wishing you luck
