I have a wrt54g v7 Linksys router...the problem is after supplying the power, only power led glows and rest of the led's aren't glowing...I did hard reset several times and once it worked(it was detected properly and all Led's worked fine) but only for 5 min and then returned to its initial state where only power led glows...now hard reset is also not doin any gud ..

what about changing the firmware? will it be possible to change the firmware in this condition and will it work after changing the firmware ..

You need power to flash the firmware.

Check the power adapter with a multimeter for the correct DC voltage.

If the power adapter is fine check the power jack. I'd resolder it on the mobo.

If it still doesn't worrk then you need to start tracing the power circits on the mobo.

Probably easier to pick up a used one and toss the old one.

Good luck!

Hi,

In this scenario i would recommend you to buy a new 4 port TP link wireless router.

As upgrading the firmware will do no good.

Good Luck.
