Lenovo Ideapad S540 Wifi reception very slow

2019-09-28, 13:37 PM

Dear all,

 

Today I brought a Lenovo Ideapad S540-14API laptop. It's wifi is extremely slow. It has Realtek 88221CE WLAN adapter. I tried downgrading and all other quick fixes. Nothing ever seemed to be working? My almost ten year old has 5 times faster speed in Downloads. Tried many times but of no avail and the result is the same. Any idea how to solve it or should I return the laptop?

Attached is the speedtest comparison for your reference. 

Currently it uses driver version 2024.0.10.202.

Apparently when I'm close to the wifi, I'm getting good speeds so does my old laptop.

Are you connected using 2.4 or 5 GHz wifi?

 

Have you tested your laptop connected to a different wifi router?

Hi Bill115, 

 

Thank you for replying. 

I have an old laptop just besides this new one and it gives download speeds of around 20Mbps whereas upload speed is same for both the laptops. To answer your question, no I haven't tried connecting my laptop to different wifi router since I don't have another but both of my laptops are connected to 2.4GHz and channel 6. 

However, I tried connecting my new laptop(the problem one) to the hotspot creaeted by the old laptop on the same wifi, it gives good speeds in terms of both downloads and uploads.

I just replaced the wifi card (Realtek 8822BE) with an Intel AC 9260 card and now it is working like a charm!!

 

I have an S540 - AMD Version. Very surprised and happy that the intel card wasn't bios locked.

Good to know that wifi card substitution works. My Flex-14API, now two months old, has slower wifi by 20-50% when compared with a 10yo Dell laptop.

 

I will probably live with the problem until 802.11ax (wifi 6) matures a bit through the year, then purchase a compatible wifi 6 card for it at the same time as upgrading the house wifi router with the new tech too.

 

Thx for posting the problem and the solution!
