Hi, Appreciate there are some historical posts around this topic but the following may be of interest. Apologies in advance for length of post.
Bought three laptops in succession in last month, two Lenovo Ideapad 330S with Intel Optane memory module plus 1Tb HDD and latest is Dell Inspiron 15 3000 with 256Gb SSD.
Fibre broadband access to the Internet provided by TalkTalk Fibre Broadband using Huawei HG633 router. Wifi/Broadband average speed check stats: Ping 10ms, Jitter 1 -2ms, Upload 10Mb/s, Download 25Mb/s.
Each of Lenovo machines returned after failing to setup reliably including erratic wifi connectivity/update problems when trying to access Microsoft services (updates, MS Store, MS Cloud, Sign In using MS account)
Second Lenovo was subject of 7 hours of remote investigation by Microsoft technical support without being resolved. Symptoms included failure to connect with error messages stating that the device was not connected to the Internet, but Edge browser and other Internet access worked OK. Connectivity was via Wifi only as no Ethernet port was provided on these models. Other wifi devices in house did not exhibit any issues.
Dell Inspiron purchased as replacement for Lenovo machines. Setup completed using Ethernet connection. Once complete decided to test wifi only connectivity, machine has dual band capability. Found same problems as with previous Lenovo machines and noticed wifi driver was same for all machines!
Checked Qualcomm QCA9377 802.11ac network driver and reset router without change, and Windows Troubleshooter did not report any problems. With failing MS Cloud sign in or “Check for Updates”, as soon as Ethernet cable re-atttached then sign in was immediate.
Investigated Ethernet and Qualcomm driver settings with following results:
- Ethernet – 100% reliable when connected or re-connected, no failures
- Qualcomm>Advanced> Prefered Band – No preference; Erratic connectivity with multiple failures.
- Qualcomm>Advanced> Prefered Band - 2.4 GHz; 100% connections with no failures.
- Qualcomm>Advanced> Prefered Band - 5GHz; 100% failures.
Not an expert but results suggest either the router, laptop hardware/driver or Windows 10 has problems using the 5GHz band. If it was the laptop (both Lenovo and Dell) or Windows 10 I would have expected to see many more current issues being reported on the various manufacturer and community blogs. So at the moment I am suspicious of the performance of the router. Current solution is to leave driver set at 2.4GHz Prefered
Has anyone else experience similar problems trying to use the 5GHz band with the HG633 router or other hardware and have any more insights or solutions?
