Not even that works on some older Laptops, i had this very problem on a housemates laptop today, We just swapped from BT to EE with a new contract and they sent us the WiFi 7 PRO router a WiFi 7 Booster and the new YOUVIEW pro box for the main TV room and recordings, anyhow, i used the new way of migrating all passwords for everything by naming it the same as the BT network we had and password and it all worked for everything, as i think it said we have 27 devices in the house connected as we have 4 Alexas, various lights, 4 mobiles atleast 4 smart tvs, 2 PCs, laptops, tablets, the list gos on,its actually crazy honestly when i was looking at the list.. But yeah my housemate came down about 2 hours ago and said i cant find the WifI network on my laptop so i thought oh itll be an easy fix, something will be turned off or hes done something, and no, i sat for an hour trying different things, the first thing i actually tried was the compatible mode as i seen that when i was setting up the router and stuff today, use that for legacy devices, i thought right thats what it will be, his wifi card for some reason cant see the new network as its throwing it out over wifi 6 now or whatever, but yeah it didnt work at all, i tried setting up guest mode, making a frequency for guests even that wouldnt show up... I didnt try disabling 6Ghz so i may try that tomoz... But yeah it got me stumped, he had to go to bed so im googling now to see if theres anything else, thats when i came across these answers, updating the wifi card in the laptop maybe was an answer that worked for someone, hopefully something will work as i feel sorry for him being the only person without internet now..
