WiFi router IPhone bug

[Deanosafc24]

Is the NO INTERNET CONNECTION bug back? But now with WIFI HUB 2 

[ferguson]

Is that what you've done then? 

[Deanosafc24]

Best way to fix this is to buy your own Router

Thank you for trying @KeithFrench , hopefully @Deanosafc24 is still to provide you with the information.

Hi @mandisa1-TT 

You are very welcome. I have been in a lengthy PM conversation with this customer, but I have had no diagnostic information back from him at all. As I do not have an iPhone myself, I am unable to do anything without his help.

[mandisa1-TT]

Thank you so much for the support @KeithFrench 

[KeithFrench]

Please note @Deanosafc24 until I receive some diagnostic reports from you, I cannot be sure this is even a bug with the router. My guess would be a power management configuration issue with your phone.

I am dealing with this independently, but cannot do anything without your help.

[Deanosafc24]

Well I may have to change ISP if this bug isn’t fixed 🫣😩 after a year and still no fix 

[amahle-TT]

Thank you, please confirm if you have tried the steps provided above?

[Deanosafc24]

Yes, the issue is back, but despite explaining the issue in detail earlier on, and the action taken so far with the original form support staff , the new support staff don’t seem to understand or want to understand what the issue really is. Mistakenly they seem to be taking “no internet access” to be a DSL/VDSL issue which it isn’t. It’s a firmware issue with Sagemcom WiFi Hub 1 and 2. 

Support Staff need to also understand that this issue does not exist with other modem / routers on the TalkTalk network such as Eero.

Hi there @Deanosafc24 Just to confirm you have no internet access at all?

[Deanosafc24]

IS ANYONE ELSE STILL BEEN AFFECTED BY THIS BUG?

On your iPhone can you try the following :

Check Wi-Fi Settings

1. Ensure Wi-Fi is Enabled: Go to Settings > Wi-Fi and make sure the Wi-Fi toggle is turned on.
2. Select the Network: Tap on the TalkTalk network name to connect. If it’s not visible, try refreshing the list by toggling Wi-Fi off and on.

Verify Password

• Check Password: Ensure that the customer is entering the correct Wi-Fi password. This can usually be found on the router or in the TalkTalk account settings.

Restart Devices

• Restart iPhone: Hold the power button and slide to power off. Turn it back on after a few seconds.
• Restart Router: Unplug the router, wait for about 10 seconds, and plug it back in. Wait for it to fully restart.

Forget and Reconnect

1. Go to Settings > Wi-Fi.
2. Tap the information icon (i) next to the TalkTalk network.
3. Select Forget This Network.
4. Reconnect by selecting the network and entering the password again.

Update iOS

• Ensure the iPhone is running the latest version of iOS. Go to Settings > General > Software Update to check for updates.

Reset Network Settings

If the issue persists, resetting network settings may help:

1. Go to Settings > General > Transfer or Reset iPhone > Reset.
2. Select Reset Network Settings. This will erase saved Wi-Fi networks and passwords.

Check for Interference

• Ensure there are no physical obstructions or electronic devices that could interfere with the Wi-Fi signal.

Its been saying no internet connection today, for 5 mins then it comes back on, BUT ITS ONLY ON IPHONE 14 

[kanya-TT]

Hey there, @Deanosafc24. Can you describe to us what is happening today.

Kanya

[Deanosafc24]

Well it’s just happened again

As I was kindly tagged by @KeithFrench 

To be absolutely clear, the connection issue is related to WiFi between the TalkTalk Hub and iPhone. It is not related to the connection between TalkTalk and the WiFi Hub, so no issues with DSL, VDSL or Fibre.

The iPhone will appear to have normal WiFi Signal but data does not appear to pass between TalkTalk Hub and iPhone. Sometimes this can happen for around 15 minutes and then clear itself. A forced restart on the iPhone or toggling WiFi off and then on can also restore connection.

For further clarity, the same iPhones in a home with TalkTalk Broadband with Amazon Eero work as normal without this intermittent loss of WiFi Data.

As the loss of data between WiFi Hub and iPhone handset is totally random, I very much doubt that this can be dealt with by forum staff. The issue could have cleared before it is investigated.

Historically the Devices Team had access to the WiFi Hub Serial Numbers and iPhone Mac Address and were able to track the connectivity between the two at times the end users logged that data was lost.

I hope that this provides some additional insight for all concerned.

Did Sagemcom ever come back with a fix for all the work which was undertaken around 12 months ago?
