TalkTalk Sagemcom Hub - WiFi Issues

Message 132 of 132

Hi TalkTalk,

 

Hopefully you can help...

 

In March 2024 I updated my iPhone XR to an iPhone 15, since then my new iPhone keeps intermittently reporting "no internet connection" despite a full WiFi signal. A reboot of the router or the handset resolves the issue until it occurs again. All other devices connected via Wi-Fi continue to function as normal.

 

This is at both my own and my mums house that have the same model Sagemcom WiFi Hub.

 

At both locations with the Sagemcom WiFi Hub my car (Volvo AAOS) will not connect to the WiFi despite a strong signal.

 

My brother also has TalkTalk Internet but with Amazon Eero, my car connects fine there, and my iPhone's WiFi functions as expected, no intermittent reporting of "no internet connection".

 

Aside from buying an OpenReach VDSL2 modem and a set of Amazon Eero, are there any other options available to me?

 

iPhone is on IOS 17.5.1 but this issue existed with previous iOS versions since brought in March 2024. I've also disabled "Private WiFi Address" within iOS at locations with the Sagemcom router in case it was upsetting things. 

 

Volvo AAOS has recently had a big update from AAOS 11 to AAOS 12 and the issue persists.

 

Both Sagemcom Routers are on the latest version of Firmware.

 

Can you suggest a "next move" please?

 

Many thanks.

Guys, I seem to remember now you mentioned this, that iPhones can be very fussy over channel bandwidth. However, that was from a long time ago.

@Deanosafc24  Out of curiosity do you remember the static bandwidth settings for 2.4 and 5ghz? 

I’m curious what your router was set too. 

I’ve adjusted two routers so far with apparent success and I’ve got a third one to do tonight or tomorrow. 

Will be interesting to see if optimisation undoes this possible fix, and also why the default setting from TalkTalk  isn’t “auto”, is there a reason such as a firmware bug?

Hi @AldridgeAndy 

 

Yes, WiFi optimisation can change the channel bandwidth, but if it is correct now (20MHz for 2.4GHz and 80MHz for 5GHz) it does tend to leave it alone. The extender should follow the router's configuration, but there are times when if the router is set to 20MHz the 266 will use 40MHz. I reported this bug some while ago now, it does not affect the 5GHz, which is OK.

Hi @KeithFrench, my understanding is that it's not the actual broadcast channel, but the bandwidth allocated to the device(s) on that broadcast channel.

 

Does Wi-Fi optimisation adjust the "bandwidth" as well as the channel frequency? I was hoping it was just the broadcast channel frequency.

 

Any ideas if you can adjust the same on the Mesh extender?

Alas, @AldridgeAndy WiFi optimisation can & will override all channel allocations that you have just set. If only we could get it disabled.....

Just a suggestion for anyone following this, I'll hopefully know more by Monday...

 

When checking the bandwidth available to the 2.4ghz and 5ghz channels on both routers I have access to they had different static values set, possibly from earlier investigations to this issue between the Sagemcom Router and iPhones.

 

I've changed the bandwidth setting to "Auto" for both 2.4ghz and 5ghz channels and also turned off WPS for both too.

 

This seems to have improved iPhone WiFi stability at my home address which also has the Fast 266 mesh repeater.

 

I carried out the same change at my mums address yesterday afternoon and when I return later today, I'll see if iPhone stability has improved there too. 

 

After making the changes you need to restart your phone or leave the house and come back later and the new connection seems more stable on first impression. I not saying it's perfect, but it's improved.

 

One for the TalkTalk staff, having made the changes at my Mum's house my car can now connect to the Sagemcom there for the first time since I've took delivery. At my house I have the Fast 266 mesh repeater, does disabling WPS and applying "Auto channel bandwidth" on the router also copy through to the extender or does the extender have it's own settings that I can't access? It would be great if I could replicate the same settings to the extender so I can allow my car to connect to my own home's WiFi.

@Deanosafc24  No it hasn’t and it’s becoming increasingly frustrating. 

Let’s hope that Sagemcom or TalkTalk bring an agreeable solution to the table shortly.

Hi Andy,

 

Thanks for confirming. I believe that the team are still investigating and trying different things to try and get to the bottom of this.
