ISP : BSNL india on EVDO
Today i purchased brand new Tp-Link MR-3420 3G/4G router for my BSNL EVDO modem..as this product is shown to support ZTE AC8700 modem...but it doesnt seem to work.. I put the right dial-up number,user name and password that i use when i connect modem to laptop and left APN field blank...The modem gets identified by the router but it just don't connect to internet,it just keeps saying "connecting.....". Also the signal strength is shown 0%... If your modem is really supporting ZTE AC8700 modem why its not working?

I am unable to connect my TP-Link TL-MR3220 router with BSNL EVDO ZTE AC8700 modem. Even though my router has the latest firmware version 3.14.2 Build 120822 Rel.57775n, which is the boxed firmware i got with my router. All the time my modem gets Identified by the router, then it shows connecting phase......and restarts the modem.........Repeats the same step every time I try to connect.

my Huawei E353 dongle/modem is not recognised by the MR3420 router. The router functions perfectly with a different dongle (E122). The E353 works fine when connected directly to laptop so I am happy it is functioning fine. Could not find a bin file for the E353.

The TL-MR3420 recognizes my modem (Olivetti Olicard 160), but it does not connect to the 3G network. I tested the modem on my PC and it connects fine. The PIN verification is deactivated and the Modem configuration is the same as I use on the PC, however it just keeps trying to connect without success. I updated the firmware to the latest version.

I have no access to the router ATM, but when I went to update, it was the latest version and build of the foirmware.I have read several reports of successful use of these two. I connect the MR 3420 to the PC, power it up. I connect BP3-EXT to the router and power it up. The MR 3420 router shows a very brief connect to the USB-based modem.: the USB light on the router stays on for about 2-3 seconds. The WLAN light on the router is on, showing a signal.
Running the setup has resulted in a couple of things. The Router's page shows that is knows the MODEM is attached to Telstra, in Australia. I do not get to put in #99# or my name and password. "Next" results in either a freeze of the Router's page "Connecting...." or I get to step through to "Congratulations, you have finished. Now connecting you to the Net"...with absolutely nothing happening on either the router or the modem. I am not sure how it thinks I am going to log in.If I do put in manual username and password, it freezes when I try to go Next.I _think_ that if the router page is frozen, it responds better if I pull the modem out of the router's USB socket.The modem works fine if plugged straight into the computer.I do remember I had a lot of trouble using a different brand of 3g router a couple of years back. Unfortunately, after I got it working, the router died.

I recently got a new email provider with a webmail. But I can not access the email from my home network. I have tried both my computers so I suspect that it can have something to do with my router. I have also set up the new email account in Outlook and in other networks it works fine, also the webaccess works fine in other networks. It seems that the problem is only related to my home network.i have talked to my ISP provider and they say that all is opened in there network. i have tried to clone the MAC address and that did not solve my problem. I also read the one could change the MTU size from default 1500 to 1440, that did not work either.

I'm unable to configure my Data Card (ZTE-AC8700). I tried with manual settings but it keeps on showing the message "connecting" but doesn't connects although my datacard is shown as identified by the device MR-3020. I'm using BSNL EVDO connection and my datacard is ZTE-AC8700. It doesn't uses any APN, only a username and password and dial number "#777" is required to connect. configuring my datacard with MR3020 ???

most service providers in our country dont have 3G or 4G support,but all the same i bought an MR3420 router in the hopes that since my modem is listed,it would still connect even if on an EDGE/2G network like YU-Kenya.But this is not the case,the router does not recognize the modem i.e it says the modem is unplugged but when i look at the logs,it indicated it detected the modem but LTE was set to zero. providing a modem bin file for compatibility under EDGE/2G connection otherwise my router will be of no use to me.

But this time, It identified the modem for few seconds, then its changes its trying to connecting, after that its change it state to unplugged. It is doing these steps repeatably. Identifying >> Identified >> (connecting) >> Unplugged. [code]

My problem is whenever I upload anything, my modem disconnects. My USB Dongle is a Telstra Ultimate 3G Sierra Wireless AirCard 312U. The problem is not present whenever I connect the dongle directly into the USB port on my LapTop.

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.

Just wonder if anyone using the same model of router and having bad connection with wireless? Its OK with the pc LAN (physical cable) connection but intermittent lost signal, request timeout when connect from notebook or iphone/ipad via wireless whether with DHCP or fixed internal IP.
I am having this issue since day 1, then upgrade the firmware by myself... Still no good. I keep the device into store send to warranty claim. After 2-3 months only get back the device, firmware being updated to above.. It seems to be OK for 1st week( i think) ... but now lost signal again.

I have owned the TL-MR3420 for about six months and never had any problems with it, 3G connection stable enough and wifi and LAN worked properly without any drops.About one week ago I started experiencing problems. Both wifi and LAN gets disabled and I need to pull the plug and do a hard reset to correct the issue. This only happens after some heavy use, many devices is connected to Wifi, streaming files over the WIfi and so on. A scenario may be the following; there are six devices back home using all using wifi. All of them are not connected at the same time, but four may be; usually three computers and one tablet. The HTPC may do some heavy videostreaming from another computer. When the streaming is over, some devices are shut down then I may lose the WIFI and LAN ability of the router.
I have tried connecting with cable after wifi were lost but no IP address where given to it and connection where refused. This means I have no possibility to access the log file in the router, and after reboot the log file is reset. Router settings is pretty much default.Is my device broken or is there any setting I may tweak with?I have updated to latest firmware and tried to change channel without success.
