I had similar issues on my MR3420. Sometimes the 3G will show as "Unplugged" and the only way to recover was to do a Reboot.
I've installed OpenWRT and I'm not turning back. Because the 3G modem still gives issues (but a lot less), I've written a cron job to reset the USB device and retry the connection every 5 minutes. And the nice thing about OpenWRT is you can customise it to do whatever you want it to do. I've added scripts to mail me reports at the end of each day, including data usage, etc.
The downside is it takes a lot of time to set up properly, and you need some unix skills.
Hey,
can you post your code or send it to me via PM?
Thanks![]()
mmmh, currently the TP-LINK routers have the widest modem support of any 3G router in South Africa and it works with about 97% of the local 3G adapters, if a modem is not supported, it can be added within a few days, maybe post a list of your supported modems or a link to the supported modems so that forum members can get an idea of which is a better supported product.
Yup - there is a problem between the modem and the MR3420 (not sure if it is the modem), but when I read that it can be added in a couple of days, I got exited and thought you had strong words to the suppliers of TP-Link and a new commitment from them to resolve issues was born.
I had a look in the Mconect supported modems list and could not find it.
After many months of frustration with the MR3420 and one too many customer complaints about often having to reset the router, along with TP-LINK seemingly unable or unwilling to fix the DDNS related lock-up problem, I have embarked on a replacement exercise.
I am returning all my installed TP-LINK 3G routers (DDNS required), bar for one MR3220 (3G sharing only application), to the local supplier and replacing them with MikroTik RB751U's.
Financially, I have lost out where I am having to replace a cheaper MR3220 with a more expensive RB751U, as I cannot very well pass this cost on to the customer (who just wants a reliable solution) at this point. Not to mention the cost of all the hours and traveling out to sites to try and figure out the reasons for the many problems over the past few months.
So far the MikroTik units have proved to be pretty reliable, especially in my "DDNS essential" CCTV remote monitoring application.
I am sure there are many, many users of TP-LINK MR3420 and MR3220's out there, who are quite happy with the product at the price point, but if you are looking for better reliability when it comes to DDNS required applications, rather look elsewhere.
As I said, I have one MR3220 still in service in a simple 3G sharing application, with no complaints so far.
The MikroTik option is great, if you can stand the learning curve and the many hours you may spend tweaking the configuration to your specific needs.
By the way OGroteKoning, I have a K4605 working in my RB751U at the moment on RouterOS v5.14

I am thinking of starting an "RB751 tips, tricks, configs and scripts" sharing specific thread if there is any interest.....

How about that?!! It is quite odd that Mikrotik, Intellinet and other 3G router suppliers try and succeed to assist to resolve issues with modems and their routers ... and yet ... everyone at TP-Link spend their energy to come up with excuses ... if they don't want or does not know how to or could not care less to help, they expext the customer to sort it out with a sniffer tool or they tell the customer that the modem is problematic! PATHETIC! What they tend to forget is that everyone was happy when a sale went through.
At the time when offered, I declined returning the router for a refund. I was stupid! I should have accepted the offer instead of waiting and hoping in vain for a solution.
Thanks Base122 for the info. I must look for an alternative router - the penny dropped ... the TP-Link and it's support is just not good enough. I will look into the Mikrotik.

Just a bit of feedback. I gave up on my TP-link router. I dont have time to struggle with a piece of hardware that fails. The guys at uniterm asked me to bring my router and dongle in, but I just didnt have the time and it seems like quite a few people are experiencing the same issues. I bought an Asus RT-N56U and my ZTE mr 668 works with no problems, no restarts needed thus far (running 8 days thus far). Yes it is a MUCH more expensive router and yes comparing it to the MR3430 is unfair, but it works and works well.

May the wors be with you
why do you guys just buy the router that don't require USB modem? The router that take SIM card won't be more convinious? that you don't need to warry about the USB modem not working with the router.
