Hi all
I have recently upgraded from a OnePlus 8 Pro to a OnePlus 10 Pro 5G and have a really weird issue concerning WiFi connectivity to a BT Smart Hub 2 router.
I have two BT Routers (two separate numbers - one in the house and one in the home office). In the office the OnePlus 10 connects to the Wifi OK but shows 'No data Connection'. Whereas the old OnePlus 8 is connected to the same router and has a perfect data connection. I have the two phones alongside each other on my desk with the 8 connected fine and the 10 connected but showing no data connection. To rub it in the 10 connects fine to the the BT Smart router in the house and any other wifi networks i care to connect to.
The only way it i can connect to the office BT Router via Wifi is to connect the old 8 and use it's hotspot. Connecting the 10 to the 8's hotspot works!!! However, this is not a long term solution.
I initially assumed it was a setting in the 10 but i thought I'd narrowed it down to an IPv4 vs IPv6 issue as, looking at the router, and comparing the settings of the 10 c/w the 8, I could see that the 8 was being assigned an IPv4 address while the 10 was being assigned an IPv6 address.
So I then turned off IPv6 on the router which, initially, didn't help. However, i then spotted that the phone, although showing as a connected device on the router, wasn't showing on the IPv4 address table. So, i rebooted the router and phone which, again initially, didn't help with the 10 still not on the IPv4 address table but still showing as connected. However, I then had a thought and, using the Wifi assistant, forgot the network and re-connected re-entering the password, etc. and initially thought I'd cracked it as the 10 started showing the the IPv4 address table and had internet connectivity.
To test, I then rebooted the phone again and, once again, upon reconnection, it's showing 'no data connection'. It's there in the IPv4 address table and is shown as connected, etc. Very frustrating.
Any ideas? Any obscure settings I've missed? All help/suggestions gratefully received.
