Model: Archer VR400  
Hardware Version: V3
Firmware Version: 1.5.0 0.9.1 v00a1.0 Build 220321 Rel.60385n

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.

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!

If it's not properly configured TL-WA850RE can cause similar behavior.

I would recommend to set TL-WA850RE with a static IP address like 192.168.X.254 (X - depends on what your VR400 LAN subnet is).

Also disable the TL-WA850RE DHCP server so you'll have only one DHCP server on your local network - VR400 DHCP server - check this story.

Before doing any tests restart the VR400 and then the TL-WA850RE.

Note: Check your WA850RE FW version and compare with the FW versions in this thread - update if necessary, then test again.

Did you update the TL-WA850RE FW according to the thread I posted, what's its FW release ?

After router hard reset did a hard reset the repeater. Configured TL-WA850RE with wired ethernet cable and now both repeater and router works fine. But I couldn't do advanced configuration bacuse somehow interface pages locked or crashed on Chrome.

Btw 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.

TL-WA850RE is a single wireless band repeater - hence the 2.4 GHz band is active only.

Good job, seems everything is working as expected now.
