Delay in downloading email and missing graphics, pictures and logos

Natsand — Thu, 26 Mar 2026 22:09:22 GMT

I have 2 iPhones and 2 iPads connected to my WiFi network. Iphone15 is great with no delays and shows all graphics, pictures and logos in emails. It does not have WiFi assist switched on so is using WiFi. iPhone SE and 2 x 10th gen iPads are struggling to download emails, do not show logos, pictures or graphics in the emails. When the emails do finally appear in inbox they may appear a day later , 2 hours later or later in the day. When I open one of these downloaded emails the wheel of death shows up and might take up to 30 secs to open it without showing graphics, pictures. When I take my devices to other networks and logon, my emails download instantly, open instantly and show all content. When others come to my house and join my network they experience similar problems. This is telling me several things but basically that my IOS devices work perfectly well when on someone else’s network and other people’s devices work ok on their networks but not on mine. Common factor is that my network is causing the problem. I have had a router swap and still have the same problems. Plusnet had me contact Apple and all my devices have had resets of network settings and diagnostic tests. Not a surprise to me because they all work fine on other people’s networks. Plusnet think it my devices at fault. Why would 3 devices show the same fault a week ago? Any suggestions anyone?

Try with Apple Relay DISABLED.

Thanks Ohilip, I have checked the 3 devices giving me grief and it’s already off but thanks for the suggestion. Will be contacting Plusnet later again.

@Natsand do you have Plusnet Safeguard enabled ? https://www.plus.net/help/broadband/how-to-use-plusnet-safeguard/

Hi Mister W, I’m not aware I have it enabled. We have been using Plusnet for about 7-8 years now and we have changed nothing in settings on my Account recently. Everything worked like a dream until last week when we returned from holiday and logged into our WiFi which has suddenly affected these 3 Apple devices.

@Natsand

In that case, maybe either your or neighboring wifi networks have changed which channels are in use and thus more interference is occuring. Are the devices with problems connecting to the 2.4ghz or the 5ghz band ?

I suggest downloading a wifi analyser app and looking at the channel allocation of your and adjacent networks.

Hi Mister W, to answer your questions: the devices affected are all WiFi connected ( not Ethernet) and are on the 5 GHz band. To muddy the waters slightly, Plusnet had me swap the HubTwo router I have had for about 3 years for a new HubTwo router they sent me about a year ago but this did not cure the problems with the devices. Rather frustratingly I have taken all 3 of the affected devices to other people’s networks and they behave perfectly! i.e. they download immediately, they open the emails immediately and shows all pictures/graphics/logos. Also my friend is here atm with her iPad and iPhone and they are working perfectly for her. If it was an interference issue wouldn’t she be affected?

also I switched on my Windows computer yesterday for the first time in three weeks which is connected by Ethernet and Mail works perfectly. Immediate download, instant opening and displays content perfectly. Maddening

My iPhone 15 continues to be the only other Apple device I have which is working perfectly🤞. Worth mentioning that all the other devices I have attached to my network (printers, thermostats, WiFi bird box, Devolo powerlines, smart tvs, set top boxes, Sonos speakers are working perfectly 🤞 can browse without a problem on Safari and Chrome. So at a loss to know why these 3 Apple devices are affected. Is it likely that having taken them abroad and on other networks has affected them somehow? If so, the iPhone 15 came as well and it’s not affected. Driving me mad!

@Natsand The three problematic devices - have you tried 1) powering them right off, waiting a couple of minutes and powering them back up? 2) If no joy with that, try 'forgetting' your network, switching off, switching on and reconnecting to the network.

Yes I have done this several times in the last 10 days. Plusnet even had me swap the router JIC. See my reply to MisterW. Maddening that all the other devices on my network still work but very thankful they are not affected. Thanks for your suggestion.

but are her devices connected to the 2.4ghz band ?

things like thermostats , wifi bird boxes are almost certainly connected to the 2.4 ghz band as they dont usually support 5 ghz.

Hvae you looked at the Hub 2 network display to check what band devices are actually connected to ?

OK. I'm at a loss, then.

I doubt this will work but on each phone go to wifi settings where it shows list of networks and delete any it has remembered which are not yours.

Another is to pause any cloud backup to see if that could be causing issues.

You mention that plusnet sent another hub a while back which you ve recently tried? Was that hub sent to solve the same issue or a different issue?

Re: Delay in downloading email and missing graphics, pictures and logos

Natsand — Sun, 29 Mar 2026 19:47:30 GMT

Different issue which had disappeared by the the time the hub arrived so I didn’t change it and kept it in reserve.

Re: Delay in downloading email and missing graphics, pictures and logos

Natsand — Sun, 29 Mar 2026 19:50:23 GMT

Yes. The 3 Apple devices with the same Mail loading issue are all connected by WiFi on 5 GHz. My iPhone 15 is also connected by WiFi on 5 GHz and is not giving me any problems.

Re: Delay in downloading email and missing graphics, pictures and logos

Natsand — Sun, 29 Mar 2026 19:52:46 GMT

Yes I’ve done this. Will try again though.

Friend’s devices are connected to 5 GHz band by WiFi You are correct that thermostats, bird box and very old printers are connected to 2.4 GHz. Yes I have checked what is connected where. The 3 Apple devices giving problems are all connected by WiFi on 5GHz band I have 19 devices connected in total. 12 by WiFi, 7 by Ethernet. 3 are on 2.4 band (bird box, thermostats, old printer) all by WiFi. Rest on 5 GHz band

@Natsand like John I'm at a bit of a loss then.

It seems to be just the Apple devices and TBH I have little experience of them but what I do recall, is that they have a propensity to use encrypted DNS ( DNS over https or DNS over TLS). That might be an avenue worth exploring...

@Natsand Which version of the OS (IOS) does each device use? I wonder if all that have problems use the same version and all that don't have issues are using another version.

Have you also tried changing the DNS on the non-working devices to something like 8.8.8.8? Or if they are set to that, clear it so it uses the DNS provided by the plusnet router?
