I have just unboxed a brand new a prebuilt laptop, everything is working wonderfully except the wifi… the network card is an Intel AX210.
I have gigabit internet, however when connected to wifi, ill get >2mbps if there is anything in between the Laptop and a wifi AP this can be a wall or door etc.
I have checked on my phone and another pc both of which get 150+ in the same locations.
If I am standing right below an AP, ill get wifi speeds of 200-300mbps off of the laptop.
I have tried all software methods drivers etc. to no avail.
Given this, I would assume it is something to do with signal strength; I have seen some people miss the wifi connectors on the card itself, could this be the case even with a prebuilt?
It could be caused by a damaged or disconnected antenna cable. Are you able to remove the input cover (5 screws) to get a look at the wifi module and the routing of the antenna wires?
Something else to check, I know you said other devices connect properly and have higher transfer speed. Are any of those devices wifi6e (6Ghz) compatible?
What wifi router do you have? Is it a 6e router? Have you checked to make sure it is running the latest firmware from the manufacturer?
Also, in W11 device manager, if you select properties for the AX210 check to see if UAPSD is enabled. If it is, try disabling.
