Apps running slowly

ON1993 — Wed, 10 Jun 2026 22:51:11 GMT

I've moved to Sky Fibre 500 this week and a bulk of devices seem to be running okay (laptop, Xbox, Alexa etc). However, my mobile device is now lagging with apps such as WhatsApp, Facebook, Instagram and even my web browser. I have seen a few different discussions touching on this but don't really understand what solution anyone actually managed to find.

Before I get in touch with Sky and inevitably get sent a new router or something, can anyone suggest what to do? I tried taking a look at the IPv6 setting and turned it off but it didn't make much of a difference.

Perhaps start by turning off broadband shield https://www.sky.com/myaccount/bb-and-talk/broadband-shield or through the MySky app.

Is this within the same room as the Sky router or is it more of a weak wifi issue?

Hi @ON1993

Depending on what brand your mobile device is, you may need to either switch Sky Broadband shield off, or disable Apple iCloud relay.

I've followed a lot of the tips shared online including turning off the Sky Sheild, turning off the IPV6 setting, restarting the router etc. My actual connection is fine on all devices in all rooms, but the speed on both Android and Apple mobile devices is awful, some apps are painfully slow. My Xbox is running fast, my Sky Q box is too, as is my work laptop. There appears to be a fault either with the WiFi router connectivity to mobile devices or something.

See my other reply on this thread, but I have tried these. I am Android (newest Samsung S26 Ultra) the Wife is on an iPhone 16. We are both experiencing the same issues but only on mobile devices. Contacted Sky and all they tried to do was sell me Sky Max which I think is poor given this is a fault they should investigate and not what I signed up for. If they don't resolve I will just leave.

As James said earlier, on the iPhone, disable Apple iCloud relay.

On your Samsung:-

Open Settings > Connections > Wi-Fi.

Tap the three dots (top right) and select Intelligent Wi-Fi.

Scroll to the bottom and tap Intelligent Wi-Fi multiple times until Connectivity Labs is enabled.

Enter Connectivity Labs, look for the Wi-Fi 7 toggle or "Enhanced Compatibility Mode," and turn off Wi-Fi 7

Thanks for the tip. I tried this and there has been no improvement unfortunately. Interestingly, within Connectivity Labs it said on the stats I hadn't spent any time connected to WiFi 7 (0 minutes) and that I had mostly been connected to WiFi 5 or 6. As I look at my phone now, the WiFi symbol is showing a 6 most of the time which I assume is WiFi 6? Any other suggestions?

See image below. Is there maybe an issue because I am connecting to the 2.4GHZ so much?

It looks like you have the Sky Max hub which doesn't have WiFi 7 (or even 6E as it's only 6 and down), that's presuming all of those stats are from home.

The Max hub tends to go for high frequency bands (149 especially) which Samsungs haven't particularly liked since the S23 and Sky locked down the Max hub to a ridiculous extent so you can't change that, bar turning it off for a couple of minutes. This causes the Samsungs to bounce between WiFi 4, 5 & 6 causing lag. It may use a lower band when rebooted but will probably change back at some point.

You used to be able (I think) to disable either of the 2.4Ghz or 5Ghz bands within the MySky app but it appears they've now locked that down to either turning both off entirely or having both. If you try, it reboots the router and re-enables both (I've just tried it). Just checked the web browser access and the 2.4Ghz band is greyed out so I can't change it at all, the 5Ghz band is accessible (although the band change option is greyed out), it looks like I can disable it entirely but not got time right now to try.

The only other thing (bar buying a decent router or turning off the max wifi after setting up a mesh system) is perhaps to try turning off the wifi power saving mode.

Open your phone's Settings and tap Connections.

Tap Wi-Fi, then tap the three dots (or Intelligent Wi-Fi) in the top right corner.

Turn off Wi-Fi Power Saving Mode

As for your other half's iPhone I can't help beyond considering the above and checking it's settings for similar otions.

Contacted Sky. Issue escalated and assured an engineer would be in touch within 72 hours to investigate. Silence. Will consider leaving

Just stumbled across this thread with the exact same issues. Moved to Sky about 3 weeks ago and generally everything runs fine - all except phone apps.

Switched from EE which google speedtest showed usually around 120mbps and everything ran perfectly. Now on Sky 300 where speedtest shows usually around 275mbps, but apps are painfully slow to load on my Samsung S26 Ultra and wife's iPhone 15.

Looking for a new car and Autotrader app is basically unusable as it takes so long to load drop down menu options each time you select a filter. Switch to 5G and it works as it should again.

Rebooted phones and router multiple times but nothing helps. All TVs, consoles, laptops, etc seem to be fine

Exactly the same issue as me, all the way through to Autotrader (I am looking for a car too)!

Still no response or solution from Sky, told me they would call back. Told me they would escalate. Absolutely nothing...

I moved to Sky recently, from Virgin, and I'm having exactly this issue.

The internet seems fine on the TV and the laptops, but there's a very noticable lag on the mobile phones; mine is a Oneplus Nord 4, and the wife's is a Galaxy S24. It takes much longer than it should to get 2 ticks when sending a message on Whatsapp, and web pages take an age to initially load. Having said that, sometimes they load up really fast. Speed tests all come back at a good speed.

I've tried resetting the modem, and I believe it worked better for a short while, but not long. Can't see an option to change the DNS address.

I haven't tried calling Sky, I may if I find time, but it's just annoying that my speed test is giving me 700+ Mbps, but it feels like I'm on dial-up when using the mobile.

Unfortunately that's not possible on domestic Sky Hubs. If individual client devices are allocated manual fixed IP addresses then they can be pointed at public DNS resolvers.

I wonder if Sky will ever see this and offer a solution. I can only imagine it is related to the hub connectivity to mobile devices in some way. I'm not technical minded enough to know how, but you'd think they would troubleshoot this and have an easy fix. @Sky is there any chance of a reply?!
