Another dropout problem

[Puzzles10]

I have this exact issue-multiple drop outs a day and my router logs look almost identical to this. I've had the black router replaced and that hasn't resolved the issue. I've got (another) Openreach engineer coming out tomorrow so we'll see what they say but 2 months on it's getting ridiculous. I work from home and we have Sky Glass, so it's really problematic. If this is a common issue you'd think there would be a common resolution...

• Router replaced
• Openreach out to check ONT/connections etc
• When dropouts occur, all lights bar power light go off and takes 5-10 mins for connection to come back up

Will report back if I get anywhere!

@Puzzles10 Your last point all the lights go out on what apart from the power light, is it on the sky Hub or on the Openreach ONT were you see that?

[Puzzles10]

Hi @JimM1, thanks for your reply. That's on the router. The ONT is always looking happy (by the time I get to it to look at least!). The other day the power light on the router did flash red VERY briefly when all the other lights went out (only saw as I was sat in front of it at the time). Otherwise, power light on router remains green, all others go off.

@Puzzles10 By the sounds off it you have the sky Broadband Hub, that is the black upright version with 4 Led's on it, Power / Internet / wifi / voice....

It should never reset itself and if you are seeing that you have to suspect two things, one is the PSU unit, but with a new hub hope you swapped it all out, the other is what is the PSU plugged into, have see them in poor 4 way or multiple Extension power strips, those can cause issues so if that is your case try another power source.....

The Norm when the Hub is re booted once you get the Power light on, and the wireless wifi light Green, ie numbers 1 and 3 as you look at them, that is a good sign the hub is up, the Internet and if using a Landline Voice they both eventually turn Green.....

I have never seen the wifi light turn off unless a hub is rebooting, so do have a look at your power first!

This link below provides information about the coloured lights on the various hubs that can help to see what is going on! If the system is also Full Fibre then the lights on the OR/CF ONT also require to be looked at!

Thank you! Yes it's plugged straight into the wall socket (ie not via an extension or anything), and I plugged it into a different socket to eliminate the power being the issue, although the Sky Glass TV is plugged into the other half and that doesn't go off (other than losing internet connection, power stays on). When Sky replaced the router, I made sure we swapped out all the cables too, just in case. It's so bizarre and not something that was an issue until mid-November. Very frustrating! Thanks for the tips.

@Puzzles10 Other devices have been known to trigger a re boot on the hub, it's an unfortnate but to find out the sky router logs need to be looked at, a complete re boot or restart off the hub always kicks the time stamp back to 1970 then once the hub set's itself with the ntp clock to the correct time, but that requires to connect and inspect the log, if you feel you can do let me know and will find instruction to do so!

I have this screen open daily, along with the router stats. I have sent these to Sky as our system up time rarely makes it to 24h! IP removed and replaced with ***:

@JimM1 @This is what happens when I try to bring up stats with the instructions you gave 

[JimM1]

@Kerry187 Sorry there is nothing attached to see!

[Bennyh]

My issues with router resets are still occuring, although seemingly less frequently than before the SR203router was replaced.

I may try and eliminate the sr203 completely to see if that is the problem. This is annoying  because I will lose the telephone line. 

Do I need to adjust the settings in Asus ZenwifiAC to get it to connect to the ONT?

I will try it and report back on findings.

[JimM1]

@Bennyh I had my SR203 right on the fibre ONT for six weeks on return mid march to sky and a refurb unit it was also, and in the whole time think there was a total off two wan drops/reset's missed both events so were late early morning hours time ones.... But i did have it split bands and adjusted the WANoE to wan only and my usual fixed IP through the Lan DHCP, nothing special, up time never dropped at all! When i was happy disconnected and returned it to the box!

5/5/25 on the SR2037/5/25 same SR2039/5/25 Final on the same SR203
