TP-Link 4G router TL MR-6500v

[TonyM2167]

Hi, my router has a web based interface. Before receiving my SIM, i was able to access the web interface by connecting my broadband ISP provider to the router (WLAN port), and my laptop to the router via a separate LAN port. The first time (and last) i open the web interface i was able to look around and get a feel for the router. When i tried to login again, i was redirected to a foreign language TP-link page instructing one toward tplinkmodem.net/ 192.168.1.1/192.168.0.1/192.168.274 to gain access to the TP-Link web interface (these were the links/ IP's that got me there in the first place.

After my SIM arrived, and i placed the SIM in the router, everything started right up, no problems, no messing around with data/voice APN's, 'plug+play'. I then typed tplinkmodem.net into my browser, and again had  access to the web interface. Updated Firmware and ticked some boxes. I did not complete the setup as there were somethings i was unsure about, so i took note and planned to go through my manual to complete the setup the next day (today).

Once again, i could not gain access to the TP-Link web interface, being redirected, no matter which solution TP-Link offer. This is obviously a problem across all tp-link models, and tp-link offer 4-5 different ways to access the page if tplinkmodem.net fails, where 1 should work.

I've opened a ticket with TP-Link, and am awaiting a response over the next few days.

Note; everything works fine, internet/phone etc, thank you 48.

If anyone knows why this is a problem, i would be grateful if they shared. I've done all the history/cookie/cashe deletes, on/off routers/modems, all of it, rain dances, chicken feathers, the whole nine yards (and the app is not supported with this model!!).

The possible solution i see, is to order another SIM from a different provider, and see if i gain access once more upon installation. As before, the 1st time with my ISP via Ethernet (then i logged out of the web interface, gone). The 2nd time with a SIM (and the sun shun again), until i logged out again, and gone once more was the access to the web interface (as allusive as fairies) it seems. Why TP-Link operates this way is beyond me.

thank you in advance for any thoughts

This is a bit vague and doesn't really clarify what exactly changed between it working ok and now not working as before.

Can you revert to the older firmware and try again? 

I can't understand why installing a SIM into the router would make any difference to accessing the web based admin interface. 

What happens if you try to access it with no SIM installed?

I would remove the SIM and disconnect the router from the other (?) broadband router and then connect a PC/laptop via a wired connection and see if you get see the admin interface that way using the raw IP address if necessary. 

Then I would change one thing at a time to see what happens and if/when things break.

Are you sure that you don't have two routers trying to do the same jobs - e.g. WiFi, DHCP, external routing, etc. and maybe causing confusion?

Hey Legend

Thank you for offering suggestions.

When i said, i "ticked some boxes" i simply meant that i saved settings such as 48/Three's. I didn't change any settings. I could see that fire walls were active and almost everything i could understand was in order.

When i said 'i was unsure' about somethings, i was referring to the VPN settings as i use Torguard/Wireguard and wanted to see if;

1. I could add Torguard/Wireguard to the router

2. If the available VPN (openvpn) in the router was all i needed, as to cancel my Torguard subscription which is due for re-newly shortly.

Now that i can not access the web interface, i can not revert back to a previous release of the Firmware.

I can understand why changing to another SIM provider may work, because when i logged to web interface from Sky, the first time, it worked.

When i logged into the web interface from the SIM, the first time, it worked, i had access again. Logic would suggest if it happened twice, it may happen a third time.

However, i take your suggestions on board, and simply removing the SIM and accessing through Sky again may work. The TP-Link router is no longer connected to the Sky modem. As stated, before the SIM arrived, i was able to connect via Ethernet cable, Sky to WLAN port in the TP-link router, and my laptop via Ethernet cable to a LAN port in the TP-link router, as instructed in my manual. And i gained access immediately, its only when i logged out i couldn't get back, the page was/is being redirected.

WiFi is turned off (permanently), i did not enable 2.4 GHz wireless when i had access to the web interface. I am EMR sensitive, this is the very reason that i am leaving Sky. When Sky executives understood, that i understood the tech being rolled out (pulsed infrared, millimeter wave), they responded by telling me, "if you choose to use Sky's equipment, you assume all responsibility", verbatim. That was good enough for me, no!.

My TP-Link 4G router, combined with a XPOL-4G antenna (keeping all data transfers outside my home, no radiation in my home). the router sitting in a Faraday cage, earthed to the ground (in the garden), and added to the fact that 48's SIM is working perfectly, i'm hunky dory, accept...i can no longer access the web interface.

Anyone who cares to look can see that this is prevalent, across almost all TP-Links models, this shows a problem exists, and existed long before i came along.

I'm going to do exactly as you suggested, that also sounds logical.

thanks again, very helpful, far better than telling me to, go to tplinkmodem.net

> When i logged into the web interface from the SIM

This doesn't make any sense to me.

Ok, i'll clarify. When using the SIM for the first time ( i had previously gained access connecting my sky modem to the tp link router via the WLAN port, and laptop to router via a LAN port, as the instructions say to do, without a SIM), i was able to access the web interface. Until, i logged out, moments later, i could not log back in, and was redirected to a Tp link foreign language web page, not interface. And other times i tried, it would simply time out, not connect, nada.

I'll try what you suggested, maybe a reset. Leaving this session now, and will give it a go tomorrow. Nite

Hey Legend

Update;

It was my VPN redirecting the page. As i mentioned, i'm not tech savvy, and my VPN was written in when i had Linux OS installed on my Windows 7 laptop, this means, if i turn off my VPN i lose access to the internet. I downloaded a browser from my software manger that translated the page telling me its was Romanian!. I remembered my VPN is sometimes routed through Romania. Turned off the VPN on my tablet, and there it was all along.

It seems to have let me in on the first attempt each time when using Sky's and 48/Three's network, and then started redirecting me.

I apologize for being a dummy, must do better.

thank you

Glad you got it sorted @TonyM2167. 🙂
