Recently I have moved from BSNL provided basic Wi-fi modems to D-LINK DSL-2750U router/modem after enough research. Setup was easy and due to dual antenna the range of wireless is better than BSNL provided routers. After moving to new router, I have faced one problem and all my limited networking knowledge as well as internet world could not help; however After I called customer support of D-Link, the gentleman immediately was able to identify my problem and provided the solution. Seems like they know the issue and troubleshooting was familiar for them. Here is the problem and fix......
I have a desktop (wired) to router with Windows 7 OS and wireless connected laptop (windows xp), Blackberry playbook and an android phone. The desktop can't ping other networked devices nor other devices can ping the desktop. The internet works perfectly from all the devices. Only issue is they can't communicate each other. This was not happening with my previous BSNL router. The issue has been isolated to D-Link router setup.
The fix is to disable "Enable MultiAP Isolation" option. Go to router setup page (http://192.168.1.1) --> Setup --> Wireless --> Wireless Basic and un-check the box "Enable MultiAP Isolation" and press "Apply" button. This fixed the problem immediately and I could ping all devices on the LAN.
I could not see any article on this by the time I am writing this, so documenting the same . Screen shot is below. I also observed that for D-link modems, there are various firmware screen shots and no consistency (for the same modem). I have highlighted the firmware for my router on top right corner of the screen shot.
Update 30Aug16:
Thank you all for your warm messages even after 3 years of my post. I did not expect this small write up would help a lot many of you. Glad to know about it.
This week I ran in to issue as internet signal is red and DSL icon is green though. BSNL folks came and verified the wires all the way from junction box etc. Finally narrowed down after couple of trials to Router issue. Temporarily used another modem and used this piece for wifi. Had to do hard reset after 3 years and it is back on track like a charm.
Does anybody tried VDSL connection on this ADSL2 Router?

Thank you very much, I was pulling out my hair.

Awesome .. save me today! ... thanks for this article
For me an additional step was required
Advanced > Advanced Wireless > Mac Filtering
had to add the MAC address of the printer here and it started working. don't uncheck Enable MAC Address Filtering this would open your local network to the internet and hacking
i had same problem, after seeing this post, i rectified . thnk you very much
Thank you so much!!! it helps to me solve a 6 months old problem

Wish i can send you a chocolate
I faced same prob
what about the similar issue in Dlink DSL-2730U ?
@Neeraj Bhai, you can always use amazon or flipkart services for chocolates :-)
@Rayson, unfortunately I did not analyze any other models and I tried to resolve my own model only.
thanks bro
Thanks a lot
Thanks a million my friend.... I owe you one...!!
This Dlink customer support is such a waste.....
Once again thanks, Thans a lot....
Thank You Man, this ensured my Hue Wireless lights becoming available over phone!
I can't thank you enough. I have gone nuts trying to figure this out.
Read the manuals, watched videos, did extensive google search but could not find any solution.
I had to go ahead and add a tp-link wifi router. I ended up using the d-link as a modem only. But the range of tp-link is nowhere near to this d-link one.
I can now happily go back to d-link only.
Thanks a lot Sir.
Just have to say - thank you.
Thanks a lot. I struggled with this for few months before finding this post...

I was trying to access My CCTV DVR (Connected on Wired LAN) from my laptop connected via wifi.
Never thought it could have such a simple solution.
Hey this helped for my migration from airtel provided router to DSL2750U.
Really happy I could access my TV (connected with wired LAN) from other devices
Very useful. I was struggling to get this working. Thanks a lot!

Hi Sudhakar, I can't add anything more than what other have said. After years together, this post has been really saving many lives and mine is the latest. Thank you so much.
was trying to connect two routers with separate ISPs via LAN and that utterly stupid stupid feature put me back 3 hours while i tried figuring where my networking went wrong.
i guess in a world of idiotic interfaces, it's much better to stick to googling instead of figuring out how shit works.
thanks a lot! had it not been for this post, i'd have ended up spending 2k on a wifi extender after saving & cursing a few more months.
many thanks
this was very usefull
Thanks a lot for sharing... Very useful
