I'd actually already posted on how to use the D-Link 2750u as a full fledged Ethernet WAN router, but it was a few pages deep in a Tikona thread and some users were getting the actual method mixed up with workarounds posted earlier in that thread.

The 2750u is actually capable of both adsl and Ethernet WAN routing. However the Indian firmware only enables the adsl WAN. So one needs to use the Middle East (ME) or Russian (NRU) firmware to enable the Ethernet WAN function (with the ME/Russian firmware one can use adsl, ethernet or 3g WAN). Please check the label under your router to identify the specific hardware version and apply the firmware that corresponds to it. Warning: You may brick your router if you apply the wrong firmware. Presently ME firmware is available for C1 and U1 versions. NRU firmware is available for C1. The NRU firmware has the mac cloning feature so you need not ask your provider to reset the mac lock (if mac lock is present). Here are the links

ME C1 v1.3


ME C1 latest


In the latest firmware, I'm having a problem getting my 3g dongle to work, which is why I've posted both versions. Once the firmware has been changed to the ME type, one can easily switch between versions (of the same hw type) using the software update page and one can choose which version works best for them.

ME U1

6.52 MB file on MEGA (Use 7zip/Winrar etc to extract firmware)

NRU C1


Applying the firmware

The firmware may not be accepted in the normal firmware update mode. Then you'll need to update it in the dlink crash recovery mode using a LAN cable (not wirelessly). Assign a static address on the PC for the ethernet interface in the 192.168.1.x series for eg 192.168.1.5

Switch router off, press the reset button ie insert ballpoint pen in reset hole under the router, keep holding the reset button and turn on the router. Keep holding the reset button for about 12 seconds after you power on the router. Now you'll see that the power led has turned red signifying that the router is in crash recovery mode. When you enter the address 192.168.1.1 on your PC browser, you find the upgrade firmware page. Just browse to the downloaded firmware file and flash!

After the new firmware has been flashed, your internet connection will not start working automatically, you will also need to set up the router correctly. Please do not apply any workarounds mentioned in other threads such as interface grouping, disabling DHCP etc

Instructions for setting up the C1 hw version router with ME firmware

Step 1:
Log into your router and under Advanced setup->Layer2 interface->ETH interface create an Ethernet interface with connection mode as default. Then go to Advanced setup->WAN Service and add service for eth0/LAN4.

Step2: If you have an internet connection with pppoe dialing such as pacenet, Honesty etc, in the next page, choose pppoe and put in username, password and service name in the next page. Also choose to enable NAT. In the next page move eth0 from available to selected gateway interface (if it's not already in selected) and remove ppp0 (if present) from selected, in the next page do the same for DNS and finally apply/save. Do thisonly if you have both eth0 and ppp0 appearing in the setup, else let ppp0 remain in selected.

Step2 (alt): If you have a connection such as Tikona, Reliance metro, cable internet (without pppoe dialer) etc, in the next page choose ip over ethernet, in the next page let the setting remain at Obtain an IP address automatically, in the next page check option to enable NAT, in the next page move eth0 from available to selected gateway interface (if it's not already in selected) and remove ppp0 (if present) from selected, in the next page do the same for DNS and finally apply/save. Do this only if you have both eth0 and ppp0 appearing in the setup, else let ppp0 remain in selected.

Step3: Then in advanced setup - 3g connection select primary uplink as ethernet.

Now connect your internet cable to the LAN port 4 of the router and you should be able to connect through any device connected through wifi or any of the other LAN ports. If you have a connection with a browser login such as Reliance metro or Tikona, the login page will show up only on the first device that you connect in each session. After you have logged in on any device, all other devices will have internet connectivity without going through the login page.

Instructions for setting up the U1 hw version router

In Internet setup, set WAN access type to Ethernet and in protocol, choose dynamic ip for connection such as Tikona, Reliance metro, cable broadband (without pppoe dialer) etc and choose pppoe if you have a pppoe dialer based connection such as pacenet, honesty net solutions etc. When setting up the internet connection, vlan id must not be given any value other than 0.

Instructions for setting up the C1 hw version router with NRU firmware (Port 1 is WAN port)

After you flash the interface will appear in Russian. Click on the rightmost dropdown at the top of the page and choose English to change the interface language.

Click on Advanced Settings at the bottom
Click on Interface Grouping in the Advanced section. Right click on the LAN icon on the right and click on setup speed and stream. There's some quirk in the interface and it's a little tricky getting this click right. Set duplex and speed to auto and save. Again hover mouse over LAN graphic and click on Make WAN. With the default option of 'Single service...' click save. Go back to the advanced settings screen. In the Net section click on WAN and add a connection. Choose connection type accordingly and choose LAN as the interface. Change MAC if required (if provider uses mac lock), (mac cloning doesn't seem to work) put in other details as needed (make sure NAT stays enabled) and click save. Internet cable goes into port 1 and not port 4 as in the case of the ME firmware
If your provider uses a mac id lock, plug in the internet cable in port 4 (port 1 for Russian fw) after completing the setup and ask him to register the new mac in his database.
Any users seeking help on this thread, please provide all relevant details (provider, type of connection) and screenshots (info and setup). Also please make absolutely sure that it's not a mac lock issue, as many users are needlessly seeking help on the forum without having got a proper mac reset from their provider.

Internet is working with wired connection through router using lan port 1. I haven't setup pppoe authentication, do I need to setup pppoe?. If I plugin the internet cable to port 4 no connectivity( no internet access). Do I need to call the hathway guys to reset the mac?
Thanks,
 
Sorry, I thought you had a pppoe connection.
If it's working with internet cable in port 1 that means it's not through router at all, it's just using it as a switch. Yes, you need a mac reset, please read first post carefully and follow it. You've not done that.
 
You still haven't provided WAN info page.
If they're saying there's no macid lock, there's an easy way to verify it. Plug the internet cable directly into 2 different laptops or PCs (one after another) and check if you're able to get internet access on them (with the ip settings as required by hathway). If both devices get access when connected there's no mac lock, else there is.
 
Super thanks Manoj! This was a great post. I recently chose to change my broadband provider from Airtel to Tata Docomo in Gurgaon. I had bought D-Link 2750U earlier and this post saved me from the hassle and expense of purchasing a new modem+router.
I have the hardware version U1 and updated to the ME firmware. I plugged in the WAN wire into ethernet port 4 (set for ME firmware) and created a new WAN connection for Tata using PPPoE and the username and password given by Tata.
I didn't face any MAC lock issue, and all devices (4 wireless and 3 wired) in my house are able to access the internet.
Now I am enjoying download speeds of 16 Mbps :peaceful:
TL;DR: For anyone visiting this page, Tata Broadand works with this D-Link 2750U by updating the firmware and plugging in the WAN RJ45 connector to ethernet port 4 (for ME firmware).
 
Hello,
I have GTPL connection and have D-Link 2750u but reading this entire forum i am still confused to use it. Please provide me step by step process to connect GTPL with dlink 2750u.
Thanks
 
Sorry, you'll have to take the effort to carefully read and understand what has already been given in detail in the first post. If you find that difficult, please get a local computer savvy friend who can help you out.
 
Step2: If you have an internet connection with pppoe dialing such as pacenet, Honesty etc, in the next page, choose pppoe and put in username, password and service name in the next page. Also choose to enable NAT. In the next page move eth0 from available to selected gateway interface (if it's not already in selected) and remove ppp0 (if present) from selected, in the next page do the same for DNS and finally apply/save
In step 2 i didn't found eth0 at any place its only showing ppp0 only, what to do please help and also what will be MAC address to be considered for unlock please help
thanks,
