TP-Link 3G/3.75G Router :: MR3420 / MR3020 - Support For 4G Modems
Feb 9, 2013
Region : Australia
Model : TL-MR3420
Hardware Version : V2
ISP : Optus, Telstra
Whilst the MR3420 V2 is sold as a 4G usb router, it appears that it does not support many usb 4G devices.In Australia we currently have the Seirra 320u, ZTE MF821 (100Mbps Cat 3) and Huawei E3276 (150Mbps Cat 4)whilst the V2 supports the first two (not the E3276), it has one major failure!It does not work at full 4G speeds.
The V2 does not appear to allow download speeds in excess of 25Mbps or uploads much greater than 2Mbps. This occurs on fast 3G and 4G networks.The throttled speed is apparently due to slow modem protocols deployed in the router. High protocol overheads mean it cannot 'shuffle data' very fast.We have developed working solutions using the Openwork platform that overcome these issues and provides speeds in excess of 70mbps.

is it at all possible to lock a 2G/3G-Stick to 2G or 3G with the TL-MR3020 (e.g. if the desired network (2G or 3G) strength is low)? If not, this would be a useful feature for upcoming firmware versions

The main router ip is 192.168.1.1 and TL-MR3020 IS 192.168.254.0I followed exactly the instructions on how to configure the TL-MR3020 from TP-Link website and everything seems ok except no internet

ISP : Three mobile data sim
Possible to use a mobile via the usb connection on a TL-MR3020. The reason being is that my mobile data plan allows unlimited tethering through my phone...yet when I place the sim from the phone in the usb modem I get blocked by the provider stating that the sim can only be used in a mobile phone. Mobile data plans in the UK are very expensive and you get very little for your money.

Your 3g router model TL MR3020 is not compatible with USB modem WM66E. Is there a workaround for this? Any existing bin files?

I'm a court reporter trying to set up a connection between my laptop and my court reporting machine, which has built in wifi capabilities. My court house has public wifi but there is always some interference which causes transmission between my laptop and machine to freeze. I was told I could create my "own wifi" between my machine and laptop if i bought a router. is this possible with this hardware?I don't need the internet or want an internet connection. I have the internal modem in my laptop. I just want to provide a connection between my laptop and writing machine wirelessly. That is, data being sent back and forth between the two. (Like your headset and smartphone connected with Buetooth). I can use the Bluetooth method to connect the two, but I opted for wireless connection because Bluetooth still can have some interference when attorneys come in the courthouse building with a Blackberry smartphone. I heard this router will provide a secured, private wifi connection between my laptop and machine.It doesn't say anywhere in the instructions that how to do this or I just don't know which method to use this router for what I want to do. Is it WISP, AP or BRIDGE, etc...?

I have problem to get pptp working. I setup pptp VPN server on my home router and configured pptp dialup on my laptop. If my laptop connect to internet directly, I am able to connect to home router via PPTP VPN. However, if I connect TL-MR3020 to internet(wired) and then connect my laptop to TL-MR3020 wirelessly, I can browse internet without problem. The problem is I cannot connect to home router via PPTP VPN any more. I believe the problem is on TL-MR3020.

ISP : Virgin Mobile with MC760 antenna
In remote areas, I use Virgin-Mobile's MC760 Broadband2Go antenna to provide Broadband to my netbook. This ISP service requires that you "sign in" with username and password to initialize the BB transmission. I would like to use my TL-MR3020 to host the Virgin-Mobile's Broadband2Go MC760 antenna to provide a wireless hotspot, instead of the hardwired direct-computer connection I have. I've gone thru the MR3020 quick setup with the MC760 but been unable to get it to connect. The 3020 is putting out the wireless signal...it's just not connected to my Virgin-Mobiles BB service...thus no www internet tie. how to use the MR3020 with Virgin-Mobile's MC760 (3G/4G) Broadband2Go antenna?

I bought this device yesterday, I am using this device with BSNL's EVDO (cdma network).It detects my modem fine, and it connects fine, and I can browse.Exactly at 50th min(few seconds difference), my net gets disconnected.I have tried all modes, connect manually, automatically, on demand -- nothing solves the concern.Changed idle timeout to 0.The device when connected directly works fine for more than 12 hours.Updated firmware to the latest 3.14.2 Build 120817 Rel.55520n.Tried Resetting the Router to factory defaults and configured again.Tried all troubleshooting steps from FAQ as in change it to WEP security, connect manually, idle timeout setting.Most importantly, tried creating a BIN file using USB sniffer and used it, even then its the same issue.

I am using the Router in 3G/4G mode, with WAN only (PPPOE) enabled. I have set a personal SSID in the Wireless > Wireless Settings > Wireless Network Name field.
I do not see the particular SSID on my computer, instead on every reboot / restart of the device a random SSID is generated. see attached screenshot. I can connect and everything works well, but I have to enter the WPA key after each reboot.

when visiting Switzerland and Italy with my German SIM card I noticed that roaming is not working very good with the TL-MR3020. The reason is that the internet provider needs to be set in the config, in my case to o2 Germany.When I travel with this SIM card to another country, I roam into other networks.As I cannot what provider is currently active (as o2 has contracts with almost every provider outside Germany) and even if I could see it I have to adjust the settings in the config if anything changes, the satisfaction effect on this trip was not very good.
Also I noticed that sometimes (only sometimes) the setting resetted itself to o2 Germany when unplugging the device, this added some extra negative satisfaction to everything.In my understanding the router should have an auto detection for the currently active network and auto setup for the dialin parameters and everything else. Like every smartphone on the planet. Maybe you can also add a setting where you can enable or disable data roaming to save people money if they do not have a international data option booked.

I'm using a 3020 to bridge 3/4G to the ethernet port on my computer. Things work fine until I also join wireless hosts (like an iPhone or iPad). The routing of traffic to both the ethernet and wireless hosts seems to cause the 3/4G router to lose the signal and disconnect all hosts. I'm using a Verizon LG USB wifi device that is on the compatible list of 3/4G devices. I'm using the latest version of the firmware on the 3020 (I believe the date is Sep 2012).

I have recently purchased the portable TP link 3020 which is a great solution for me in order to get wifi for multiple users till I get through the long process of getting ADSL in Turkey.The thing is that the 3G bundle Turkcell provided me with is not identified by the modem, so I looked it up on the internet and I found out that I needed to add the bin of the bundle, I searched within the list published on TPLINK website but without any luck.... finally I found the bin I was looking for in another country list... mine is Huawei E353 and the one I found is Huawei E353s2. Anyway I added the bin and still not luck identifying the bundle, I finally resorted to upgrade the firmware which I hate because I always worry of the bad consequence of failure, and unfortunately I was right! Once I upgraded the firmware, I couldn't get connected to the router, it keeps asking me for the key, but without any success! I tried hardware reset by holding the WPS button for 5 seconds as suggested in the manual, but any further success!

I'm trying to replace my old router with the TL-MR3420 but I cannot reach Internet.
I get "Internet" directly by a Cable into my apartment. This Cable is connected to the WAN input. Then I connect my computer to one of the LAN ports. (The Cable Connections are done exactly as on my previous router.)
The setup on my PC (running Windows 8) is as described in the manual (IP address automatic and DNS server automatic).
Internet doesn't work and I cannot reach the router from the browser using 192.168.1.1.
I'm not using any 3G and of course I have restarted the router (and PC) a couple of times. I thought I could just replace my old router with the new one... but NOT.
