NetComm-M2M NTC-40WV Firmware Update
We’ve been having a connection problem with this router — a computer on a wireless connection will often find the router but not the internet, though it worked on last login. Any wired connections can see the interwebs. So I guess that’s a ‘wireless connection problem’.
Power cycling (have you tried turning it off and on again?) the router solves the problem, but is not a very satisfactory solution.
So I thought I’d try a firmware upgrade.
Old firmware was 1.9.1088 (or something), quite old. So in a way that was good — more chance that the new firmware will solve the problem.
Went to https://support.netcommwireless.com/product/ntc-40wv and downloaded https://support.netcommwireless.com/sites/default/files/firmware/NetComm_M2M_Family_Release_FW18.104.22.168_NTC-40WV.zip. This is probably the last firmware this (now unsupported) device will receive.
Unpacked the archive.
Logged into router (http://192.168.1.1) as root.
Now, the main trick is that when upgrading from 1.x.x.x series firmware to 2.x.x.x, we must first install something called appweb-large-file-
This is within the downloaded archive, so it’s OK. Don’t go hunting around in the ‘net for it.
In the browser interface to the router, went to System → Load/Save → Settings and saved my existing router settings to a backup. (Accept the given file name!)
Then went to System → Load/Save → Upload and browsed for the ipk file, then uploaded and clicked ‘Install’. (The instructions are in a PDF that’s also in the archive; read that instead of this.)
The 2.x.x.x series firmware is a single big file, where earlier versions contained two smaller files, hence the need for the preliminary upload.
Then browsed again and chose ntc_40wv_22.214.171.124.cdi.
Uploaded and installed.
Waited about 4 or 5 minutes.
Shiny new status page and rearranged browser interface to the router appeared. Was active; I could browse the web etc, so all looked good. But — had our problems with wireless connections gone away?
<<One week later>>
Now, after a week of observing the ability of machines to connect, do we still need to reboot the router regularly?
It seems … a lot better!
