@Panical 

Hi, for your issue, may I know if your router supports 5GHz band? 

If so, can you check if you can find any available networks for 5GHz band around your house?

If you can see the other 5GHz band networks but can't see your main router's 5GHz network, please move the PC closely to the router to check if you can see it?

If not, please change the 5GHz band Wi-Fi settings like name and change the 5GHz channel to be 36/40/44 to check if it works?

If it still doesn't work, please tell me the model number of your main router?

BTW, may I know if other wireless devices can see the router's 5GHz network?

Look forward to your reply.

@Kathy_Z 

 

My old laptop detected 5G.

My phone detects 5G.

The adapter doesn't.

 

Note that I have now moved city, and I won't be having a router for a couple of months. I will use mobile data. So, I can't look at my router or change any settings.

Thanks.

@Panical 

Hi, sorry that we didn't provide help in time and help you solve the issue.

Since you have moved to a new city now and didn't use the router, we can't check the router's settings and provide any help.

If you came back and want to use the adapter again, please feel free to contact us again when you have problems using the adapter.

We would like to provide the prompt help as soon as possible.

@Panical Check you device version and wifi channel number, FYI, EU version doesn't support channel higher than 140
