wifi issue in 2 different product

[kirionet]

I am having issues with two netgear products:

1. D6200

It was working perfectly when I suddenly encountered the following issue:
Any device which doesn’t have Wifi N, (therefore only can use 2.4ghz) are not able to see my SSID. While other devices that use 5ghz will.

I tried the following:

• Move the location of the router in a totally different area.

Result: the 2.4ghz SSD appeared for a few moments but was on and off

• Updated the firmware, and reset the device various times

Result: Nothing changed, same issue

• Changed all the channels of the Wifi

Result: Nothing changed, same issue

1. DGN3500

The wifi connection comes and goes.

I tried the following:

• Updated Firmware

Result: Same issue

• Reset

Result: Same issue

Any idea? Should I consider these two devices as faulty?

Thank you

note:

My pc is running on a windows 10.

2.4 device are a huawei android phone and a asus tablet with windows 10

The DGN 3500 is installed in a different place in a different house

802.11n is able to operate on both the 2.4GHz and 5GHz bands.

A device which does not support 802.11n may have problems associating with the 2.4GHz band if in the router settings you have set the Link Rate to anything above 54Mbps.

Sorry about the confusion. What I meant was: The devices that don't support 5ghz (but have wifi N)

Well it might still be worthwhile trying the various WiFi Link Rate options, and changing the 20/40MHz option.
