I found out that on a brand new Lenovo ThinkPad E580 (My tester), after upgrading the wireless driver of the Realtek 8822BE Wireless LAN 802.11ac PCI-E NIC to version : 2023.70.213.2018, I can no longer connect to the enterprise radius wireless.
It keeps saying : Can't connect to this network.
I rolled back the driver and it works, any ideas ??

How Do You rolled back driver version? At my Yoga this option was disabled (greyed)?
I have problems with this Realtek 8822BE Wireless LAN 802.11ac PCI-E NIC in Yoga 730 -13IKB, the advice I got from Lenovo Facebook to set in windows setup: System->Power & Sleep ->Additional Power settings ->Change Power Plan -> Change Advanced Power Settings -> Wireless Adapter Settings -> Maximum Performance. (curse microsoft for this hurdle). But this does not work immediately, wait for warm up 5-10 min, no guarantees

My wifi stops working when on battery after 10 mins or so - needs wifi adaptor to be reset - yes I have the switch off the adaptor box unticked - other people are reporting issues in various circumstances having issues with Realktek.
It is about time Lenovo came out with a fix because suggested fixes are not working. I am about to pack up this E580 and going back to my old 2011 HP as I have no issues with it.

I have been having connectivity issues with the latest RealTek PCIe driver. The WiFi connection will just drop out for several minutes and then come back to life. (I opened a command prompt and pinged a known IP address - using the /t option and could see the Request Timed out and Destination Host unreachable messages).
I went into Device Manager and selected the RealTek Network Adapter and opened the driver tab and then rolled back the driver to version 2023.70.213.2018 All appears to be stable now. Interesting that the current driver version lists stability as part of the reason for the change. For me that version (I think ends in 2.101) is anything but. Hopefully Lenovo will look into this and come up with a fix.

Short anwser is the issue continues. To make the issue worse Lenovo Support is clueless.
After searching other Lenovo forums concening the Realteck 8822be I found a solution to replace the Realteck card with an Intel 8265 card.
The card is a Lenovo stocked part or available from most reatailes like Amazon and NewEgg. The price is in the sub $30.00 range. Simple plug and play. Update the Intel drivers for both WiFi and Bluetooth and no more issues.
Very upsetting the number hours wasted with Lenovo Support plus the 3 on-site repair visits when the solution was on the manufacture' webiste.
