Good day.

Normally, during the set-up, if you failed to detect the 5ghz of the Huawei router, we would suggest you could change the wireless channel of the router;

And if you can see the 5ghz of Huawei and also input the correct password, and there is no access control or mac filtering on the router, later I would send you another firmware that you could have a try.

Thank you!

Good day.

Thank you very much for your kind reply.

In this way, we might need to follow up your case via email, and please have a check of your message box;

By the way, may I know how long have you had the RE305?

Is it not able to detect 5Ghz since you bought it?

And except the 5Ghz of Huawei HG8145v5, can RE305 detect any other 5Ghz network?

Is the 2.4Ghz working properly on the RE305?

Thank you very much!
