Please call dlink tech support at 877-453-5465. just an advise on how to handle the call when you reach dlink tech support (agent); do not agree to call back after you troubleshoot with them (they'll be giving you a case id reference# and be advising you to check your pc or call "who" and call them back to continue the troubleshooting). insist to the agent that he need to resolve the problem asap (by the way, agents are not allowed to drop the call or they'll be dead-history!). and if the agent still insisted you to call back, ask for a "senior level technician" to finish the job (escalate the problem).
fyi: dlink tech support handling time to resolve a call is 15 to 18 minutes only. if you reach that 15-18 minutes (max) time the agent will think of a way for you to call back (advising you to check with your pc manufacturer, check with your ISP, call microsoft to update your software, etc... non-sense!) they need to do this in order to reach their handling time (agents need to reach 21 to 25 billable calls, and billable calls are "solution provided", "resolved", and "dropped call"). ---- believe me, i was one of them and repented.

How to update whole firmeware of tplink for w8901g


Sameer, First thing to do is establishing some facts of this router. Please look at the labels at the bottom of the unit and let me know the firmware version. Something like v1, v2 or v4. Pls look here for the example http://www.tp-link.com/lk/Article/?id=46.

You now have to connect the router to a pc with a network cable, that pc is NOT connected to the internet. For instance with a separate laptop, disable the wifi. The network cable connects the router (one of the LAN connections) to the pc.
Invoke a browser and write in the address line 193.168.1.1 with ID admin and password admin. This should open the service program from the router. Go to Firmware upgrade. And follow the rules. Generally you have to check the latest firmware in the TP-Link site and download that file to your pc. IF you have any questions we are always here to help.
Success, Fred

Internet problem


The best way to resolve this one is to upgrade the firmware of your router, firmware is the software inside your router so better check the manufacturer's site for the latest firmware for it...

TP-LINK TD-W8920G (A) ver 2.2 UK new firmware > build 080227n ?


My solution:

Go to the "Security" option and click to "Incoming" rules. By default, all WAN traffic blocked, but you can create "ALL" rules, just left the source and destination ip address and port blank. This means ALL ports and ip like the firewall off.
