Bought a new wifi 6 router. Several devices would not connect to it

Router is a TP-Link AX3000. I managed to get my main computer connected to it, and get internet, but my other devices would only connect to the network, (but got no internet.) I called TP-Link customer service, and asked for help troubleshooting. The individual I spoke with suggested I configure the router to use google dns servers: 8.8.8.8 for primary, and 8.8.4.4 for secondary, (as pictured below.)

And I ll be damned if it didn t work. I now have the internet for all my devices…but at what cost. I mean this is google we are talking about. Google is resolving domain names to ip addresses. Or rather knowing every website I visit…not sure I like the sound of that.

Well, try other DNS servers, I sincerely doubt it’s limited to only those 2 google dns servers.

This is all new to me. Is there like a list of dns servers one can choose from?

4

I recommend Quad 9 for DNS.

5

Im interested why you recommend Quad 9.

6

Mainly because of the privacy. No ip information is logged. They’re also fast and reliable servers.

7

With all due respect. Do you honestly believe that? In reality you have no way of knowing that is true. If push comes to shove, my bet is, all bets are off. I use Mullvad vpn, and they say the same thing, but no doubt, if powers that be want to know they will know. That is my belief.

At the end of the day, you have to trust somebody or go completely offline. I don’t trust Google, they are known to stalk you around the Internet but I choose to trust quad9 until proven otherwise because they have a track record of resisting court cases. And winning.

Well you either can’t trust anyone or you have to trust someone.

I also have a TP-Link wifi 6 router (1500). The local DNS works fine.

$ nslookup        
> server 192.168.0.1
Default server: 192.168.0.1
Address: 192.168.0.1#53
> google.com
Server:		192.168.0.1
Address:	192.168.0.1#53

Non-authoritative answer:
Name:	google.com
Address: 142.250.176.206
Name:	google.com
Address: 2607:f8b0:4006:80e::200e

What do you configure your TP-Link to connect to? Another router or the cable modem? Post the screenshot of the “internet” tab.

If you change TP-Link to use local DNS, is your PC able to connect and lease a valid IP from the DHCP server? Post output of,

$ip a

and

$cat /etc/resolv.conf

I see no tabs. There are just icons, and text links. There is an internet section, and in advanced there is also an internet. What one do you mean?

12

Advanced->Network->Internet

Looks like your router is connected to your ISP’s modem directly? The upstream DNS servers are, 162.150.21.51 and 162.150.8.51. Sowehow, those two DNS servers are not resolving properly.

$ nslookup
> server 162.150.21.51
Default server: 162.150.21.51
Address: 162.150.21.51#53
> google.com
Server:		162.150.21.51
Address:	162.150.21.51#53

Server:		162.150.21.51
Address:	162.150.21.51#53

Name:	yahoo.com
Address: 96.99.224.231

If you’re connected to the ISP’s modem directly, my suggestion is to ask them what is the right DNS to use. 162.150.21.51 and 162.150.8.51 look a bit odd to me.

15

Well there lies the rub. One can rationalize to their hearts content and become oblivious to all of it. Why not?

I have my own modem. It’s an Arris Surfboard.

17

That’s from your ISP?

18

No. I bought it. It just happens to be comparable with my isp.
Compatable

Well, check the settings in the modem. It’s acting funky. I’d connect directly to the modem provided by the ISP.

Hahaha. What you talking about? You need to rest your neck. I think you are tired.
