Looks like you don't even need the hardware version, there was only one... Go to
this page, click
Hardware version 1.0 and click the Download link in the
FIRMWARE and note where it is saved (most like in your Downloads folder) and the filename is
FW_E2000_1.0.06.001_US_20140310_code.bin
Next, in your web browser go to your router's IP address... Most likely it is
http://192.168.1.1, and unless you have changed it the username and password are both admin. Then navigate to
Administration - Firwmware Upgrade, click
Browse and select the firmware file you downloaded above, then click
Start Upgrade button, and wait for the process to complete. The entire process is detailed
here.
That's all there is too it... BTW, the newest file for that router is still 2014. Honestly, if it was me I would replace it anyway.
Release notes for firmware versions are below, there is really only one thing noted that may apply here and I highlighted it for you. The reality here is if the phone works on every other WiFi network except this one, it is an issue with this router.
