One night this week my laptop stopped connecting to the wifi at home. My mobile devices were still connecting with no problems. I rang Telstra, my modem was checked and declared to be working. The Telstra support told me they believed my laptop was the problem as the mobile devices were connecting.
i employed an independent IT technician to give my laptop the once over.
Tested Laptop - Driver Uninstalled & Updated, still Could not See Telstra SSID on Modem
Tested with Mobile Devices in Home but they only connected to 5Ghz Network.
Assumed it was the Network Card within the laptop which had failed.
USB TPLink WiFi Dongle purchased.
Tested and Couldnt Detect 2.4Ghz Network, Went upstairs directly next to Modem, Even with NEW WiFi Dongle only 1-2 Bars Showed Up.
He indicated that the Telstra Modem has a FAULT with its 2.4Ghz Network and that it should be replaced by Telstra.
Telstra do not accept this and are telling me that it has to be the laptop. What do I do???

If you scroll back a few days ago, you'll read that several people commented they were having issues with 2.4Ghz since a recent update.
If you have the Technicolor version of the Gen 2 modem (DJA0231) this is probably due to the latest firmware update (18.1.c.0443-950-RA)
There are a couple of post where people have lost the 2.4 Ghz WiFi band after this firmware update.
Suggest you contact Telstra support again and report the modem's 2.4 GHz band as faulty if you have this model modem. Even if you don't have this particular model of the Telstra modem the 2.4GHz band is still faulty. The firmware version is displayed on the LHS of modem's login page.
Thanks. Telstra are replacing my modem after I referred to the amount of communication on this forum re my issue.
You were a big help.
