Hold in the reset 'button' with a paper clip or something else small for a FULL 30 seconds, keep the paper clip in place, power the router off for 30 seconds, then power the router on again, still holding the paperclip in place for another 30 seconds. That's 1 minute 30 seconds total (3hours in cat time) but that should force the router into a factory reset. Then go to etc and all should be well" - hope this helps. Dave

If you are doing a firmware upgrade:
1. Navigate to the default home page of your router.
2. Look for a setting such as "System" "Updates" "Settings"
3. Follow the on-screen instructions after having selected update firmware (note this feature may try to query the manufacture's website for firmware updates as the first thing it does.)
4. Check for a "browse for firmware file." or "Browse"
5. Navigate to where you saved the firmware upgrade file and select it.
6. Choose a button for "update firmware now" or "apply this firmware" or something of that effect.
7. Let it run but DO NOT unplug the router or stop the update while it's processing it. This could render the router useless.

If your router isn't set up this way. Let me know.

Dlink Dsl -2730u

Two possible causes for this:
1. Power fluctuations has caused the AC to DC power supply to over supply the router with current. This will damage the router's electronics. Solution to this is to buy a new router.
2. Updated firmware: if you updated the firmware and the new firmware got corrupted during the download, you could experience that problem. I will suggest to revert back to a previous version if this occured.

Configuration Lost After Restart

there must be some memory on the board that isn't functioning properly. Try to do a factory defaults and set it up and see if it sticks. If it doesn't then I would suspect bad circuitry or perhaps firmware issue. You can upgrade your firmware may resolve this issue.

Here is where you can download your manual and download firmware. Do not update firmware through wireless connection!

To reset the router, locate the reset button (hole) on the rear panel of the unit. With the router powered on, use a paperclip to hold the button down for 10 seconds. Release the button and the router will go through its reboot process. Wait about 30 seconds to access the router. The default IP address is When logging in, the username is admin and leave the password box empty.

The updated version of firmware is level 1.02NA You can check which level of firmware you currently have installed and if its a lower number you can try to update it if factory defaults don't do the trick.

Firmware upgrade faild!!!

you got yourself a pickle. updating firmware (or flashing) it's a very critical process and you only do it becuase you have to (an nothing else), not completing a firmware update usually will cause irreperable damage to your unit so be prepared to replace the router.

now the only thing you can try is to

1. make sure you have the right firmware update (the one that is specifically for your router model and revision). find the router model and revision (usually at the bottom of your router) and get the right version from the router manufacturer and nowhere else and try the update again since you can still access the configuration page. section 5.11.2 on manual (link below)

2. you may also want to attempt to reset your router to factory defaults, section 5.11.3 on manual

your router's manual

good luck! and if you need a new router go for a linksys one!
