Slow wifi on new Optimus

Hi, I have just had my new Optimus 15" laptop delivered, but I'm getting very slow speeds on the wifi; about 2Mbps. My previous 8 year old laptop and my phone are getting 20 to 30Mbps.

The laptop has an Intel Wi-Fi 6 AX200 and Windows shows it is connected at 5GHz on 802.11 ac.

Can anyone offer any advice on how to speed this up?

Hmmm.... ok, have you got access to the router?

I'd suggest plugging in with LAN cable to the router. Do a speed test with the wifi turned off, just to verify it's the correct speeds through the LAN.

Then go into device manager, find your wifi adapter in "Network Adapters" and right click and "uninstall device"

Then reboot and log back in. Windows update will automatically install the relevant driver for the wifi.

Then disconnect the cable, move a sensible distance away from the router, and connect again to wifi and retry.

Hi @SpyderTracks

I'll need to borrow a LAN cable from work tomorrow, and then have a play tomorrow evening. My old Windows 7 laptop is still reporting about 22Mbps on Ookla over the wifi.

I'll provide an update later. Thanks for your help.

Assuming the speeds are ok when cable attached (showing that it's a wireless problem) I would open up the laptop and find the wireless card (it's probably under the keyboard) and check that the two antenna cables are properly attached to it. We've had at least one other case on here I seem to remember, where these had not been attached at all during building.....

With a LAN cable connected I got 25 to 30Mbps last night. I took @SpyderTracks advice and uninstalled the wifi card and rebooted. Subsequent tests on the wifi showed about 1Mbps. I have raised a ticket with PCS.

Okay, things have moved on a bit, but the waters are still a bit muddy to me.

I took the laptop to work and it connected and registered 90Mbps on Ookla. At home I was still only getting 0.2 to 2.5Mbps.

I have also opened a ticket with Plusnet, my broadband provider, and had a long phone call with them last night. They split the 2.4GHz and 5GHz channels, giving each a separate SSID. The laptop connected to the 5GHz and registered the same poor speeds, even on the BT Wholesale speed test site they suggested. However the laptop completely refuses to connect to the 2.4GHz channel at all. This despite there being 8 other devices that connect to it and get good speeds.

At the moment both sides are doing what they can to help, but I really don't want to end in a position where each suggests it is the other's problem.

@SpyderTracks and @ubuysa - The muddy waters are becoming clearer. PCS confirmed that opening the case would not invalidate the warranty or return policy, and sent the service manual for the laptop. I opened it up and guess what? One of the antenna is disconnected from the wifi board, and I am unable to get it to re-attach. This must be the 2.4GHz one.

I have updated PCS and am awaiting their response.

They are a very tight fit and it's darned fiddly too. You have to press quite firmly. Getting advice from PCS is good but you want to connect it yourself rather than have to send it back.

Hello Chris99,

First of all, I am sorry to see that the wifi antenna is disconnected on arrival. I know you have already raised this with our call centre but could I trouble you to send me the order number via PM so I can look into this personally?

Hi @moosEh

I have started a forum conversation with you. I take it that was what you meant by a dm?
