EMG3525-T50B: single laptop can not connect to wifi

jasonkaler

Hello

Router: EMG3525-T50B firmware V5.50(ABPM.2)H0

Problem Laptop: ASUS, windows 10 x64 19042.1110 with Intel Dual Band Wireless AC 7265

When I connect to the zyxel router with wifi, it says "cant connect to this network"

I can connect to it with a LAN cable

The wifi network on the device is working fine except for one laptop.

Other laptops and mobile devices can connect to wifi okay.

The problem laptop can connect to other wifi devices okay.

If I reset the router, the ASUS can connect, but will lose connection, sometimes after a few minutes, sometimes after a few hours.

After the ASUS has disconnected, it can not reconnect without restarting the router.

Things I have tried:

In windows, under Network & internet settings > Network Reset.

At command prompt: netsh winsock reset

also, ipconfig /release , ipconfig /renew

I've reinstalled network drivers

Created a new AP with a different name

Tried 2.4Ghz and 5Ghz

Tried DHCP and fixed IP address

Tried disabling IP6

If I have ping running while connecting, 1 packed will get through when it connects, but then after that the following packets fail with "destination host unreachable"

If DHCP is enabled, the laptop will be assigned an IP address

The problem has been impossible to find because making changes on the router usually restarts the wifi on the router and then the laptop can connect, only to fail the following morning again.

I don't see any related errors in the windows logs or router logs

any ideas?

Hello @jasonkaler

If it only one device that is having problems accessing the WiFi then it sounds like it would be an issue on that device.

My suggestions are check that you have entered the correct network security key for your WiFi into Windows 10 on that ASUS device, and also try running the Windows 10 network troubleshooter.
       - right click on the WiFi icon on your ASUS device and then left click on Troubleshoot Problems. and see what Microsoft suggests.

Kind regards,

1. Update the system OS and minor updates

2. Verify on router if you have channel 2.4G: 40 and 5G: 44 (less interferences)

3. Update the wifi driver card with last updated from support-model asus's website

4. Use the wpa2 for more standard

Hello @Scorpione

Is there a channel 40 in 2.4GHz band? I think that it only goes up to 14, and channels 12, 13 and 14 are not allowed worldwide, see https://en.wikipedia.org/wiki/List_of_WLAN_channels#2.4_GHz_(802.11b/g/n/ax)

I agree with you about channel 44 in 5GHz band, as 5 GHz band is currently less used.
 https://en.wikipedia.org/wiki/List_of_WLAN_channels#5_GHz_(802.11a/h/j/n/ac/ax) talks about the 5GHz band plan and regulations.

Kind regards,

I have an asus laptop with the same problem, did you get to the bottom of this?

I also have the exact same problem, and I also have an Asus laptop, but different network driver: Realtek 8821CE Wireless LAN 802.11ac PCI-E NIC. The laptop was able to connect to the router normally for a month before the problems started.

I never got to the bottom of this.

This router is now sitting unused as I had to switch to one that works with all my devices.
