To locate another device node, the firmware driver should walk the device tree relative to itself, not by enumerating all device nodes for a match. A user may have plugged in multiple instances of the device, and the firmware driver should only update the device with which it is associated. Typically, the device node to be located is the parent or sibling of the device node on which the firmware driver is installed.
For example, in the diagram above with two device nodes, the firmware update driver can look for a sibling device to find the function driver. In the diagram immediately above, the firmware driver can look for the parent device to find the primary device with which it needs to communicate.
The driver should be robust to multiple instances of the device being on the system, possibly with multiple different firmware versions. For example, there may be one instance of the device that has been connected and updated several times; a brand new device may then be plugged in which is several firmware versions old.
This means that state such as current version must be stored against the device, and not in a global location. If there is an existing method to update the firmware EXE or co-installer, for example , you can largely reuse the update code within a UMDF driver. Skip to main content.

He is more of a solution provider rather than a typical content writer. You can contact him at admin bpedia. Can someone confirm that the issue is resolved? It looks to be the same version of FW that my modem already has with the troubles. I have unch of these modems purchased from BSNL and having this problem. I just upgraded your FW on one of it and waiting. I see that the FW version details remains the same. Normally this problem comes after one day of resetting the router.
Can not open Ok daren, do one thing. Put ip address manually on your LAN. Oops, i think the the problem is within the modem. Daren, are you getting the ping reply from your modem? When there is a problem or want some MAC to add the list, I can not access the modem. All the way I have to reset, reconfigure and when there are 25 modems at a place you can imagine the trouble! Hi Shardool, i suggest you to reset it one or two time more.
Sometimes it needs multiple hard reset to make it work. So go ahead and reset it one more time. Make it Quick question! Is this a good modem?
Should I replace it and buy something like TP-Link? I did upgrade the firmware and the issue is resolved. However, I feel like Rs is too much for this modem. What do you think? Also, may I know the source of the firmware file so that I can keep tabs on the update. If you rewrote the firmware, kudos to you! Can you share the source on GitHub?
Hey there, glad your problem was solved. As long as it is working, keep it. Besides it has 5 years of warranty period too. Still if you are not satisfied or you need some extra fancy features, you can go with D-Link modem router rather than TP-Link.
Nope, i did not write it, i got it from one of my friend. Thank you for your quick response Prabhakar. Is it possible to get the source code of the firmware?
Not sure about that. I have tried to contact the manufacturere several times, but there was no proper contact information provided anywhere. Sorry about that. I actually tried it myself and then found your blog. I was hoping that you could contact your friend and ask him how he patched it. I see a lot of forum with unanswered questions. Hope you could help! Drop me a mail at admin bpedia. I would let you know if i got anything worth sharing. I was not getting internet today.
Modem LED for internet was red. He told me that there is virus attack , and a lot of BSNL modems in our area have been affected. He asked me to bring the modem tomorrow to BSNL office to reconfigure it.
I was not so patient to wait one day to sort the problem out. I tried to enter the modem by typing IP address Then I searched web sites for help, and met yours. The device will reboot automatically after the upgrade has been finished. Some firmware updates will restore your router to factory settings.
