After some considerable difficulty and strain, I managed to reconfigure my RE200 for my new modem.  All is good, seems to be working better than it ever did before.

 

But. 

* I connected via wifi to configure it, but the SSID has disappeared

* My laptop doesn't have a LAN connection so I can't connect by wire

* http://tplinkrepeater.net/ doesn't work 

* I installed Tether but it says "make sure your hardware is supported" (it is), but it refuses to connect.

 

So I can't access the configuration interface now.  How do I access the interface again?

Is your cable modem in a combo unit with your wifi router?

 

Anyway, I find that using a LAN connection from a laptop makes the process easier. Buy a USB-to-LAN adapter for your laptop.

 

I have a RE305.  After it is configured and connected to my wifi router,  http://tplinkrepeater.net  no longer works. That domain appears to be IP address 192.168.0.254 but when the extender is connected to my wifi router, the router assigns the extender a new IP address.  

 

I have not figured out how to connect to the the extender's UI to change other parameters.

 

Anyway, you will need to push the Reset pin on the RE200 and start over again.

 

EDIT:

I spent more time with my RE305.

Reset it.

Wait a minute.

Disable wifi on the laptop.

Connect with LAN cable from my laptop.

Type in http://tplinkrepeater.net in Firefox.

Once in the tplinkrepeater.net website, one thing I did differently is to go to the Network tab and select Use the following IP address and set the IP address to 192.168.0.254

I think it defaults to Obtain an IP address automatically.

 

I also disabled 5GHz band since I am using the extender for my outdoor security cameras and they mainly use 2.4GHz.

 

The RE305 Extender seems to be working.

Yes.  I just recently got upgraded to an Arris TG3452.

I have one currently in use, but I could borrow it.  Or maybe I could connect the RE200 to a LAN port on the wifi router ??

OK...

* I reset the RE200 and waited a bit.

* I disabled wifi.

* Borrowed the USB-to-LAN dongle, connected it to LAN, and plugged in RE200.

* Went to http://tplinkrepeater.net.

* Ran through the setup and let it reboot.

* tplinkrepeater.net still works, but only when connected via LAN.

* I set the address to 192.168.0.254.  Now I can access the tplinkrepeater interface by that IP address.

* I installed the RE200 in its proper location, connecting by wifi.

 

I didn't disable 5G because I use it.

 

So I think I'm in better shape than I was.  Thanks for the tips!  (IEEE488, that takes me back ...  I worked at HP decades ago, when we called it HP-IB!)

> (IEEE488, that takes me back ... I worked at HP decades ago, when we called it HP-IB!) Ah! HP was king of test equipment. Those were the days. I bricked my RE305. I installed OpenWrt on it. Didn't like it. Then used OpenWrt to try to install the TP-Link firmware. Sigh.

Ouch! Well I appreciate you not bricking it until after you described your process for me. :)

From what I can tell, I will have to try to rescue it via the serial port.

 

Remove the cover and solder 3 wires to the J2 connector's GND, TX, and RX, except there isn't a connector; just thru-holes in the printed circuit board.

 

I have all the equipment needed including a serial port to USB adapter.
