Dear Sirs, I have the following problem with Linksys router wtr54gl: after an unsuccessful attempt to install new software, I have no communication with the Internet and can not reset the router to factory settings. Expect some advice. Credit: O. Boev
You must connect to the router via Ethernet cable for setup/upgrade. If you pooched the upgrade buy a new router… software fixes/hacks are not really our thing here. If this Answer is helpful please remember to return and mark it Accepted.
Here’s the Linksys support page for your unit WRT54GL Wireless-G Router It has all you should need to answer your questions.
Try by resetting your router and re-configure it again. Please note that your all saved setting shall gone once you have done hard reset so i would suggest if your using ADSL then get your PPPoE account setting from your ISP first and then do this.
