Intermittent/Limited WiFi issue Lenovo X1 Carbon (Gen 3) with Intel AC 7265

Intermittent/Limited WiFi issue Lenovo X1 Carbon (Gen 3) with Intel AC 7265

 

Just started to set up my new laptop that I received a couple weeks back, but it is failing to connect to wireless router. It does connect briefly, but then disconnects and sometimes has 'limited' connectivity. I have tried to diagnose and change settings. This is out of the box. Upgraded everything when I did have some connectivity... still doesn't work.

Type: 20BT007AAU
Warranty: to Sep 2018
 
Windows 10 Pro, has a Intel® Dual Band Wireless-AC 7265
Driver: 18.20.0 (Latest) - according to the ThinkVantage Update and all Latest Windows updates.

Tried:
a) Driver rollback: 18.11.0
b) Disable Norton Internet Security (a new year subscription)
c) Change Power setting, so WiFi is always max
d) Other solutions on this forum - changed to g and go back to default a/b/g in Advanced settings

e) Modifying below settings:

---

Intel(R) Dual Band Wireless-AC 7265

802.11n Channel Width for 2.4GHz - Auto
802.11n Channel Width for 5.2GHz - Auto
Ad Hoc Channel 802.11b/g - 6 ( was 1, no diff)
Ad Hoc QoS Mode - WMM enabled (was disabled)
ARP offload for WoWLAN - Enabled
Bluetooth(R) AMP - Enabled
Fat Channel Intolerant - Disabled
GTK rekeying for WoWLAN - Enabled
HT Mode - VHT Mode
Mixed Mode Protection - RTS/CTS Enabled
NS offload for WoWLAN  - Enabled
Packet Coalescing - Enabled
Preferred Band - 1. No Preference
Roaming Agressiveness - 3. Medium
Sleep on WoWLAN Disconnect - Disabled
Throughput Booster - Disabled
Transmit Power - 5. Highest
U-APSD support - Disabled
Wake on Magic Packet - Enabled
Wake on Pattern Match - Enabled
Wireless Mode - 6. 802.11a/b/g


Nothing seems to work. Don't need dual band -  just want the WiFi to work and be stable as per every other WiFi laptop or device I have had on the network

Router (DIR-655) is completely fine, I have used it for years, and many other laptops connect and are stable. I put it 1-5m and still it is failing. Reading all the issues this card has a history of issues - why would Lenovo be still putting it in these laptops? What alternative replacement are there that actually work - can I get this changed under warranty?

 

Is there anything else I can try?

Just to give this an update.

 

I am still without a working Laptop Wi-Fi. Since raising this issue and contacting Lenovo, they finally managed to ship out a replacement part which was installed by a mobile technician and declared Dead on Arrival.
