RUTX09 Industrial Router - Review, Install and General Guide

This a post detailing my install and opinion of the RUTX09 router from Teltonika. I am using this at home, I run a business from home, and we have 3 kids home schooling during lock down.


A few weeks ago we started having problems with our MR6400 router, it the TP Link router was freezing and locking up.

We were using the router very heavily at the time, so when searching for a new router I included the phrase "industrial" hoping for some heavy duty offerings. This a 3G 4G router for mobile broadband.

Firstly if you would like to watch a video instead, please do:



When searching I was met with a mixture of offering from Cisco (around £1000) and a new company Teltonika, which I hadn't heard of. These range in price from £150 to £350, and the hardware specifications were good, and that couple with ability to use open source linux software on them made the decision.



I got mine from NetXL, the delivery was very good, next day, even when ordering in afternoon. I had previously bought a ponty XPOL antenna from them so was sure it would be sent quickly.

The RUTX09 router is well built, with an all alloy construction. It runs on an ARM processor (which is the same they use in iphone).

It is fairly self explanatory putting it together. I was little surprised that there was no wifi, but that's my fault for not checking. Easy to set up using old router.



The inclusion of a GPS antenna, leads me to think perhaps this router is vehicular applications (?) not sure.

The router includes a small tool to remove SIM tray and install, which is neat.

In any case I was soon logged in to the configuration interface which, first lands on a 4 stage setup. I had the router connected wired to my main PC, and I noticed the speed was very good, the internet felt more snappy straight away. Download speeds increased from 30MB/s to around 40MB/s.



HOWEVER, none of the wireless access points seamed to have internet access, and network connectivity (when looking at client list) was patchy and sporadic.

Note: My home network consists of:


  • Router RUTX09
  • Netgear Switch (5 Port) to
  • 100M ethernet cable to 
  • Netgear Switch 20 Port to 
  • Power Line Adaptor (Netgear)
  • To Access Point
  • Additional Access point (also via additional Powerline adaptor)



I tried in vein for around 7 hours to get the network operational, I switch everything on and off again (the whole system), checked all IPs, MACs and DHCP settings. I reluctantly upgraded firm wear, which went OK!

Then I found a little setting on Network > LAN > Edit LAN > Relay Configuration

Whether it was luck, or this was the correct setting for wireless access points I do not know. After enabling I noticed the firewall rules had automatically changed. So perhaps it is a pre-set for firewall configuration.



Any how, now the RUTX09 router is up and running is it an absolute sledge hammer. It can run 2 HD TVs, 3 Video Conference Laptops, and my main PC. It is rock solid.

With the same antenna, and same reception our old TP link router could not handle web use and TV watching at the same time, and could not handle 2 x HD TVs at once. The failing must have been on the TP Link Router's behalf, as the down load speeds were alway 30MB/s plus, so should be enough for 2 TVs and a few laptops.

So all in all it works very well, and I would suggest give this or another Teltonika Router a whirl. Since setting it up, everything has been working A-OK, with no crashes or evene delays.

They seam extremely well made . . .  they just need a few setup presets for dumb asses like me!

TP-Link TL-MR6400 Freezes or Crashes

TP-Link TL-MR6400 Freezes or Crashes the Symptoms


About 2 years ago we moved to mobile broadband, the TP-Link TL-MR6400 has been very good over that period, up until around 1 month ago when it started freezing and or crashing.

Typically in our case this involved a loss of internet connection, and when you log in to the router (which appears still to be running) the status page is partially blank. As pictured below:


The problem can be fixed by rebooting from the GUI (system tools > reboot) or by switching off the router and back on, either on wall socket or button on the back.

I should say that this crash and freeze behaviour has coincided with the CV19 lockdown, which means we are running TVs, and 3 computers through this TP-Link TL-MR6400. I am also using an external antenna.

Things I have Tried to Fix This 

I have tried a few things to solve this problem. They are just shots in the dark, and some I am not sure if they have worked, as time will tell. To be clear none have the below have worked, I am just checking off options. 

Detach Unnecessary


This first thing I suspected was some sort of power overload (don't mock me I just try things out based on imagined scenarios). So I unplug all but one of the ethernet cables, and then used a network switch to take from there. Previously I was using all 4 ports, now just 1 so did this work? This did not work. 

Overheating

Next I thought perhaps overheating was causing the problem. So I rigged up a "wind tunnel" cooling system, as pictured below. There are vent holes around the perimeter of the casing so air should pass through the router as well as around it. 



It is basically a box, to force air around and through the router housing. I used an arctic cooling F12 fan, there was a notable draft through the box, and the previously warm router was stone cold. This did not fix the problem. 

Turn Off 4G


Again, thinking about putting less stress on the router . . . . what about turning network mode to 3G only? This can be done on router config page. (Network > 3G Only) 

I have just tried that and will report back in a few days. Update: Wow. 3G is really slow. Not really an option to put up with that. 


Other Ideas

Here are some other ideas explored:

External Antenna is Causing Crash?

I would say no. We had used a cheap external antenna for around 1 year, with no problems what so ever. The system had not been changed and yet the problems arose. 

Overuse Causing Crash?


Does too much bandwidth cause a crash? I am not sure, I haven't really seen a correlation. The router typically crashes in the evening. This would coincide with watching TV . . .  which is a heavy use, but on the other hand we have watched TV on 2 TVs for long periods without it crashing.

Please chip in in comments if you have answers or ideas.
