TP-Link VR1600v DHCP Fails

Hi there,

I’ve discovered if I statically assign the time capsule an IP address outside of the DHCP range of the TP-Link, everything now works smoothly. I use the TP link for WiFi and have disabled WiFi on the Time Capsule. The Time Capsule is set up in bridge mode and connected via Ethernet cable to the TP link.

E.g.

Time Capsule IP: 192.168.1.201 (manually assigned)
TP-Link DHCP range: 192.168.1.100 - 192.168.1.199

If I don’t do this, after a few days the TP link stops assigning DHCP addresses to new devices and this is why they cannot connect to the Internet or any other devices on the home network.

Hope this helps!

Ummm, how do I manually assign an IP address to my time capsule?

You can download the Airport Utility that allows you to manually configure the settings on the Time Capsule. You can find it in the Apple App Store or if you are using Windows you can search for it on the Apple downloads website.

Thanks! Since I have given the Time Capsule a fixed IP address my ethernet connections have been rock solid. I have not required to reboot the modem since the change. I can't get around the wireless network issues/conflicts if I set up the Time Capsule and the Archer modem with identical names. Even when I tried using different bandwidths for Time Capsule and the modem.

My current setup is 2 differently named wireless networks with the Time Capsule in bridge mode and with a fixed IP address. This seems to be working fine at this stage.

Shane:

 

Have a few customers with TP-Link Archer VR1600v.

After a period Modem fails to issue iP addresses - DHCP failure.

Pseudo PSTN stops working.

TP-Link say it is TPG's problem.

Power cycle returns modem functionallity. Could attached timer to cause power cycle Daily but this seems unnessessary as I have already set each modem to reboot every 3 days.

 

Is there a firmware upgrade?

It seems to be a conflict with other devices that have DHCP capabilities. E.g. Apple Timecapsule, Access Points/routers on the same network. Rule those out and statically assign them an IP address outside of the TP-Link DHCP range as a workaround

Is there a firmware upgrade? Some Tp-Link Vr1600 Modems don't have a firmware upgrade option under System Tools.

 

In all the Tp-Link TPG supplied modems I am dealing with that have this problem there are no DHCP server conficts.
