Question Archer vr400 AC1200 v.3 wireless problem

[garasakal]

Hi,

tp-link Archer vr400 AC1200 v.3 (Firmware up-to-date) modem has a wireless problem on both 2.4GHz and 5GHz connections.

Wi-fi clients cannot establish a continuous and stable internet connection on 2.4GHz or 5GHz. The connection is constantly interrupted and we receive the "connected without internet" errors. But when connected to tp-link TL-WA850RE range extender connections are continuous and stable.

On Archer vr400 I tried the change the wi-fi channels, first on auto and then at the recommended numbers, problem presisted.

Archer vr400's wired connections are 4 security cameras's router and a laptop via ethernet. But this problem started long after the camera system installation.

ISP provider states that there is no problem with our connection, tp-link support states that if there is interference in our connection, this may be the source of the problem.

Could the range extender be affecting the wireless broadcast of the modem?

Thanks in advance.

Very strange. Are you sure you are connecting where you think you are. Are the ssid different or the same on the extender.

What the message "connected without internet" means is the wifi is actually functional. This would be what it would look like if you unplugged the internet cable coming into your house.

Use the IPCONFIG /all command and see if you get IP addresses. If you get valid IP see if you can ping the router/gateway IP.

Hi,

I've checked all ip's on tp-link Tether app. All wired and wireless connections had correct ips that it should.

Called tp-link TR support, hard reset modem with reset button, unplugged the TL-WA850RE repeater, setup modem from zero; bang! problem solved!

Seems like TL-WA850RE distrups Archer VR400's wireless signals!

Btw I've seen some threads on tp-link forum that TL-WA850RE corrupts Archer VR400 signals;

All you neighbors are constantly stomping on your signals. It might get slow but they can't actually prevent your from also using it.

Now it could be related to WDS which is what repeaters use to connect to the main router. Not real sure I never use repeaters because of all the strange issues with them. BUT issues with WDS would cause the repeater to have disconnect issues but the directly connected devices work fine.

What doesn't make any sense is how can you use a repeater that connects to the router using the same exact wifi signals as your end devices also are using. To the main router the repeater in many ways functions as a end device. If the signals from the main router were be damaged then the repeater itself would lose connection to the main router.

Maybe reconfigure things so the repeater only uses say 2.4g only. Leave the 5g signal so only the main router uses it. The 2.4 and 5g are separate radio chips so they will not affect each other.

In our case router's signals were corrupted not repeater's. Although you could get wireless wi-fi only if you connect to the repeater.

After router hard reset did a hard reset the repeater. Configured with wired ethernet cable and now both repeater and router works fine.

On router both 2.4 and 5 is active, on repeater just 2.4 is active and DHCP is off. Tested wi-fi signal interferece on tp-link Wi-Fi Toolkit app on mobile and result is good.
