[Apple Watch] Unable to Check for Update - Not connected to the internet error

Here's what I did that worked:

1. In Bluetooth settings select any Apple Watch that is paired and select forget device
2. Turn on then off airplane mode for good measure
3. Retry pairing and update

Hopefully this works for you guys too

if You are connected to WIFI 5GHZ on Iphone, change it to WiFi 2.4 GHZ and setup Apple Watch

This MUST work :)

Hey guys so I was having the same issue as everyone else but on an apple watch series 4. I went ahead and attempted EVERYTHING! Hard reset watch,Hard reset Iphone, reset network settings on iphone. I even signed out of icloud at one point. So the one that finally did it I think I reset watch then iphone and attempted to pair. It gave me the same message as always "Unable to Check for Update - Not connected to the internet error" but this time I just hit the try again like 15 times back toi back to back! no lie it seemed like everytime it looked longer for the update until it freaking worked! updated to watchOS8.0.1

I hope this was not a fluke and helps some ppl.

REMEMBER hit the "Try again" button back to back to back mine worked like on the 15th time.

I had my Apple Watch connected to my old phone. When I got my new phone and tried to connect it and I got the "Unable to check for update error. I contacted support and they weren't able to solve the issue.

The ONLY thing that worked for me was updating my Apple Watch using my old iPhone (phone that the watch was perviously connected to) and then resetting and pairing it to my new phone. Annoying but it worked.

Whilst not directly related to an Apple watch 5, my Apple watch series 3 had this same issue of the not connected to internet error. I tried all the things mentioned in this thread and others.

Here is what worked for me:

1. On your iPhone go to settings>wifi and tap the "i" next to the wifi network you are connected to.
2. Scroll down to DNS and change it to manual.
3. Delete every server entry on the list.
4. Add the servers "1.1.1.1", 1.0.0.1" "8.8.8.8" and "8.8.4.4". Then hit save.

Now try and pair your apple watch - it should work, mine went ahead and downloaded the 8.0.1 update for my Watch series 3.

Tried pretty much all suggestions on this thread. Nothing worked until I turned off cellular data on iphone. Just had wifi on. It worked!

I solved this issue by turning on automatic update on the watch settings/general/software update/ turn on automatic update ( on the watch not the phone) apple watch 3

Forget all the answers, all of them are wrong. The real solution is that your watch need 50% battery charge to continue. A real Apple failure to show this error instead of telling you that.

I tried everything with my series 4, ended up connection to my samsung hotspot wifi and download started perfect, i think my modem is only swt to 5gz and for some reason update only works with 2.4gh

There are a whole lot of things tried in this forum - I think this really has to do with a 2.4 GHz wifi signal. This appears to be the ONLY connection to the internet that "counts."

To resolve - I went into my router settings and switched OFF my 5 GHz signal (only leaving my 2.4 GHz signal active) - as soon as I did it started working (To force the connection to wifi I did disable my Cellular data.).

I think most other cases suggested were when people got lucky and happened to have been connected over 2.4 GHz (like leaving things connected overnight, etc.) There are certain cases where a dual band router will switch the signal you're on and sometimes you can just get lucky. I do have to admit when I was at work I did multiple hard resets, etc. but nothing worked until I purposefully connected over 2.4 GHz.

iPhone 11 - iOS 15.1 Apple watch series 3

I found an answer!!! On your watch watch go to settings, software update. Then open on your iPhone and it will find the download. Resetting phone and watch did nothing. Opening software update in watch first fixed the problem immediately…idk why. lol

I solved this by choosing manual set up, after trying all other mentioned fixes. I would suggest restarting both devices first. When you see pairing animation on watch, click on the little i then choose to pair manually. Do same on iPhone. This worked for me.

GUYS I FINALLY FIGURED IT OUT, if you can't pair your apple watch because of something along the line of not connected to internet, I figured out how to fix it! So basically, you want to make sure that the Watch app is allowed to use Wifi and Cellular. Go into settings, and then Cellular, then scroll down until you see the Watch app, then click into it and make it is selected as WLAN & Cellular Data, then go back to whichever way of pairing you like and BOOM, problem solved! (This comment was from someone on youtube, It worked for me and I’m sure It’ll work for you)

I've tried almost everything mentioned in this thread but no luck. I'm trying this with brand new Apple watch series 3 & iOS 15.1. I don't understand why it is so complicated. Even service center guys couldn't help. Very frustrating experience. Tried following things: Changed language & region, hard reset, reinstalling app, multiple device pairing, 2.4ghz internet, Any other trick make this ***** Box working.
