Model: Archer AX1500  
Hardware Version: V1
Firmware Version: 1.2.0 Build 20210420 Rel. 39971(4555)
Hi,

Since yesterday evening, most websites are not working for me, except for Google and a few others, such as YouTube, Facebook - prolly working via IPv6.

Things I have done so far:

- cleaning the cache and cookies in all browsers
- cleaning my PC with CCleaner
- internet connection attempts with AV turned off and Windows firewall turned off
- restart the router, restart the computer
- DNS address changes from automatic to 8.8.8.8 and others
- update the router firmware
- the following commands:

Type "ipconfig / flushdns" and press Enter.

Type "ipconfig / registerdns" and press Enter.

Type "ipconfig / release" and press Enter.

Type "ipconfig / renew" and press Enter.

Type "netsh winsock reset" and press Enter.

- disable IPv6
- router reset and setup from scratch - fixed IP provided by my ISP
- restore the system to the state from 2 weeks ago

None of the above helped. I went to sleep, I got up in the morning - everything works. I figured it was a DNS problem on the ISP side, but they said they were fine. A few hours came and now it does not work again ... I called them, they did not know anything about this problem. Their tech guy will be available next a week.

Operator: local ISP

Cable Internet connected to the desktop

TP Link Archer AX1500 router

The problem also occurs on a company laptop connected to this net via Wi-Fi - same websites do not work with exceptions. For example, Onet.pl works on a Laptop, on a desktop - not. fcbarca.com doesn't work on both. ERR_CONNECTION_TIMED_OUT

Interestingly, I can ping all these pages without any problems. I can also fire up and play WoW online.

2.4 ghz mode 802.11b / g / n mixed

5 ghz mode 802.11a / n / ac / ax mixed

Fixed IP 192.168.0.41, DNS and gate 192.168.0.1, subnet 255.255.255.0 - as I was told by my ISP and how it worked until yesterday.

Interestingly - all websites WORK through a proxy, e.g. https://hide.me/pl/proxy

In the attachment ipconfig etc. from now, that is, from the moment when it does not work. I have no way to upload the same file from the moment everything works for a comparison.

Thank you in advance for any help.

It looks like a DNS issue.

Try this settings on your AX1500 and see if that will help:

 

 

 

N.B. Just FYI - you have a double NAT in your network judging by your trace route test:

 

C:\WINDOWS\system32>tracert -d 8.8.8.8

Tracing route to 8.8.8.8 over a maximum of 30 hops

  1    <1 ms    <1 ms    <1 ms  192.168.1.1
  2     2 ms     1 ms     1 ms  192.168.0.1
  3    11 ms    13 ms    13 ms  212.91.0.250

.....

Probably this is due to an ISP modem/router connected before the AX1500.

This may not be an issue for you, so if everything works then you're good to go.

@terziyski 

Hi, thanks for the update.

 

I wanted to adjust these settings but I am using static IP so they are not available. And when I set these on the network card instead of automatic DNS then nothing changes.

 

Funny thing is the same situation reoccurred and again everything is fine in the morning - all sites work. I am attaching the same file but from now where the situation is normal, maybe that will give you a hint what has changed and what could be the root cause.

 

I can bet it will go down again and I will try to notice at which hour it broke and I will have a look into the event viewer - maybe I could find something interesting there.

If you are using a static IP on the Internet port, then that's the setting you should do:

 

 

I suppose your LAN settings are like follows:

 

 

DHCP server:

 

 

The log file is the same - nothing informative about the issue.

Instead pinging 8.8.8.8 you could "ping cnn.com" for example to test the DNS resolution, when there's a problem and when there's no problem.
