wifi 5 GHz problem with MacBook Air

[medicol]

I have  Compal CH7466CE cable modem

Internet 200 Mbit/s

wifi 2.4 GHz and 5 GHz both running

with 2.4 GHz all run good

with 5 GHz MacBook Air see the network, but has a speed of 3 Mbit/s (channel 120)

inspecting what is attached at the network with the cable modem, MacBook Air does not result in

Using a PC no problem

Anybody noting a similar behaviour?

Forcing channel 40 speed become top but still MacBook Air is not depicted as attached by cable modem

Hello medicol,

did you do a factory reset already? Can you check the 5GHz WiFi with your PC? What speed do you get there? How far away are your devices from the router?

Kind regards,

Claudia

if I get connected with my PC to 5 GHz I get normally 200 Mbit/s as per contract

with MacBook sometimes with 5 GHz less than 1 Mbit/s

In both case I am in front of modem at 3 meter distance

No, I did not try any factory reset, also because then I loose all my setting concerning the network

Anyway I can do it if you ask me to do it, let me know please

@Martin59 I received a newest modem, Technicolor, it has also the steering option to be set up. I truly appreciate it.

Till now it seems better and MacBook Air is connecting good at 5 GHz, BTW I steered it at 5 GHz to extensivly test.

I keep reporting for sure

Have a nice weekend
