My modem is suddenly showing a red light for mobile signal. It’s been like this the last few days and the internet doesn’t work. What can I do to fix it? It’s worked previously

MY  Telstra Smart  Modem gen 2  is showing a fixed white light on the front this evening . Download and upload  speeds are what I typically receive

Recurved Smart Modem Gen 2 as my second replacement after 3 different Fast 5355 modems that were supposedly “faulty”. Have plugged in new modem and it has been flashing white in front for about an hour and lights on back are flashing green. I understand that flashing white on front means firmware update but surely it shouldn’t take 1 hour? Have turned Oof and on multiple times. Called Telstra and they told me there’s a fault in NBN but it’s fine when I plug old modem back in. Any ideas? So frustrated.

@BradR05 - Just some thing for you to try: Make sure that you are using the new power pack with the new modem. You can try returning the new modem to factory defaults by holding in the reset button on the back, count to 15 before releasing. Allow 10+ minutes for the modem to complete the reset and check for firmware updates. The time that it takes can vary depending on how the modem is connecting to the network at the time. Leave the modem turned on overnight. Also, I recommend not interfering with the modem if it is currently doing a firmware update.

@Shellock Definitely has the correct power brick. Cables were already plugged in when it came. I have left the house and left it plugged in so it will be on for a few hours before I’m back. Did try to factory reset but holding the button did nothing

@Shellock what’s the general time it takes to download and install an update? I assume that’s what it’s trying to do just taking a very long time. When I rang Telstra they said there was a fault but I’ve since plugged old modem back in and it was fine then swapped back and it won’t work.

@BradR05 It could be that the update server is having issues atm. I'd be inclined to plug that modem in when you go to bed and see how it is the next day.

 

Sometimes when I have had issues with hardware not resetting I would turn the item off for 10 minutes. Then while holding the reset button in turn it on. I don't know if this will help with the Telstra modem as yours is the first post I have seen whereby it won't reset (Might be because it has part of a firmware update, so its stuck in limbo until finished)?

@Ozmoz not sure. No matter what I’ve done all it does is flash white on front and flash green on back lights. Might try holding reset then powering. Then I’ll try leaving it over night. But the lady I spoke to from Telstra was clueless. Didn’t know what the modem looked like. Kept referring to names of the lights from previous routers which have changed. And she kept saying it’s solid white yes? And I had to repeatedly tell her no it’s flashing white. And as usual they read their generic lines from their customer service manual. Best one was when she said “Is your modem connected to power?” Nah the lights on it power themselves. Smh...

@ashliem this is great but could you please add a picture of the lights also (or maybe the quick start guide)? I am attempting to help my relative who lives in a different state and need some reference material.
