Slow wifi (even with fast speeds on other devices) 6th gen X1 Carbon

2020-08-29, 23:40 PM

Posted this earlier with a stupid subject line and got no responses - trying again with one that says more about the issue. 

 

Hello, 

 

My thinkpad is 2 years old. The wifi has been running slow and I've been having issues with my zoom video calls. At first I thought it was an issue with the router -- but upgraded the router and then realized it was only my laptop that was having the issue. I will check my speed on Ookla on the laptop and get something like 60 mbps while I am getting 350 mbps on my phone, ipad, other laptops. Sometimes I am getting as low as 15 mbps We have a 1 G plan from FIOS so 60 mbps is very slow. 

 

I ordered a t-link nano bluetooth adapter to see if that helped, but I am not getting any better speed with that. I've updated the driver on the original wifi adapter, reset the adapter, updated the laptop on Lenovo advantage, tried pretty much everything I could find online (with my limited understanding of computer issues). 

 

Any ideas on what might be happening and how I can improve this? 

 

Thanks in advance,

Jennifer

The built in Intel(R) Dual Band Wireless-AC 8265 or Intel(R) Dual Band Wireless-AC 9260 should be connecting at 5Ghz and providing pretty good speed.

 

I would try the latest driver from Intel, which is slightly newer than the one on Lenovo's site.   

 

Lenvovo version for AC 8265 is v20.70.16.4

Intel version for AC 8265 is v20.70.17.1

 

Lenovo version for AC 9260 is:  v21.70.0.6 

Intel version for AC +260 is: v21.90.3.2

 

Note:  Make sure to select the 64-bit versions from the links below.

 

Windows® 10 Wi-Fi Drivers for Intel® Wireless Adapters Version: 21.90.3 (Latest) Date: 5/20/2020

https://downloadcenter.intel.com/download/29520/Windows-10-Wi-Fi-Drivers-for-Intel-Wireless-Adapters?product=99445

 

I would also recommend that you update to the latest Bluetooth driver from Intel at the same time

 

Intel® Wireless Bluetooth® for Windows® 10 Version: 21.110.0 (Latest) Date: 8/4/2020

https://downloadcenter.intel.com/download/29790/Intel-Wireless-Bluetooth-for-Windows-10?product=99445

 

FYI   If you bought the TP Link UB400 Bluetooth 4.0 Nano USB Adapter, it is is just a Bluetooth adapter and does not provide WiFi connectivity.

 

Also, if you have not already done so, reset your WiFi Router, because many problems can be resolved by just doing that, even when other devices are working fine. 

 

Edit:   I see where you replaced the router, so a restart is probably not needed. 

 

 

Best of luck,

Thanks for responding -- any other ideas? I followed your instructions and then restarted the computer. Just ran speed test simultaneously on my laptop and iphone using the same tower (is that the term?) and here are the results: 

 

 

Download speed -- 49.98 X1 Carbon, 321 iphone XS

Upload speed --   31.72 X1 Carbon, 239 iphone XS

 

The TP link was a TP mini AC600 USB 2.0 wifi adapter. The computer recognizes it (can choose it -- listed as Wifi 2 -- as an option for connecting when it is plugged in -- but doesn't help speed. Had read that as one way to deal with slow speed so gave it a try. 

 

Should I try replacing the wifi adapter? And if I do, is it worth doing it myself or should I take it to Best Buy or some other tech place? 

 

I have a home business and can't afford the glitches. Plus about to have two kids tapping into the wifi for remote schooling.  I've put a LAN in for my office, but sometimes need to be in another space where I only have wifi. 

 

Really appreciate it. 

 

Jennifer
