Consistent latency issues

Inbound862 — Fri, 25 Jul 2025 19:36:30 GMT

Every day around 8pm my ping spikes to around 1700ms when it usually sits idle at 12-13ms. I've tested whether this was an issue with my pc but it appears everything on my pc is completely fine. I've just run a speedtest from two other devices when I noticed the spike and the latency is showing around 1700 from those devices too so it's clearly an issue with the wifi itself but not too sure what to do about it

@Inbound862 Switch all the wireless devices off one by one until you find it! If you have channel interference from external source then nothing you can do about that!

@Inbound862 sounds like you are suffering from a burst of radio interference. As the effect is short lived it could be being caused by a switch sparking when being turned off or on or a faulty device like a microwave. While the source could be outside your home so unavoidable it is more likely to be local so consider what happens at the same time for example someone is using an old electric kettle to make a hot drink.

Hiya, I'm honestly not sure at this point

I hadn't noticed during the week as I was at work but it's not just at 8pm that this spike happens. It's consistent throughout the day, doesn't appear to have any clear common factor for when the spikes happen. Today it's happened 8 times so far between 2pm and 7pm, not a single time when the ping spiked was anyone using any kitchen appliances or downloading on other devices so I'm very lost to be honest. The signal strength seems to be averaging around 85 dBm if this is relevant at all

@Inbound8621 That is a very poor signal strength no matter what, the higher the -db then the worse it is, took a look at mine just now on Netspot and connected at -28db which is excellent in the least, mid 60's you are heading into connection area issue's. Router twenty foot away through a brick wall and a door is at -62db which is fair!

Just had a look on NetSpot it;s currently at -68, The router is in the garage through a brick wall on the other side of the house to where I am. Is there anything you recommend trying? We never had this issue until recently it seems to have just gone downhill. Could a firmware update help potentially?

@Inbound8621 Are you the same person from the start as @Inbound862 just so i can re-read and follow from the start!

I am yes! Original post was made on my parents (account holder) account but I don't have login details so had to make my own 😅

@Inbound8621 Run the following below ping command on your pc as where it is via and admin command prompt. It is a 10minute run time and when it is finished paste the 4 line result just as you see it further below. I will run the same on mine FF500 wireless wi-fi connected starting it off now and post my results up!

ping bbc.co.uk -n 600

This below is what i want to see from you.....

Ping statistics for 2a04:4e42:400::81:

Approximate round trip times in milli-seconds:

@Inbound8621 Ten minute run, wife on hers wireless, daughter no doubt on the PS5 gaming wireless, plus my laptop running the test.

Ping statistics for 2a04:4e42:400::81:
Packets: Sent = 600, Received = 600, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 14ms, Maximum = 72ms, Average = 16ms

And this was the start as the network settled which is fairly normal for a wireless connected.

Just seen this, running the test now and will post once it's finished!

If I notice that the connection massively spikes I'll run it again and post the results for that, at the moment it seems relatively normal

@Inbound8621 Agreed from that posting nothing to dramatic and only one lost packet! and below a very intensive speed test that does a very detailed testing.

When you get time draw up the details what hub, what devices connected Ethernet / Wireless wi-fi, Extenders/Mesh/Sky Q etc anything that throws the spanner in the works, reason why the Hub is in the Garage and important what type off connection Fibre/Copper + Speed you have. You can PM me if you wish to keep it private!

@Inbound8621 Take a quick look up and down the results to see what the spike timing looks like, pretty sure it's going to be wireless related. Sent you a PM.

Edit:- What hub do you have connected and are you all wireless with no etherent connections as you say the hub is elsewhere located.

Re: Consistent latency issues

JimM1 — Sun, 27 Jul 2025 20:36:14 GMT

@Inbound8621 You have the SR203 hub from sky running a FF500 fttp service, and the FW was updated on that hub i would say about 3 weeks ago.

Since you know how to look at the hub, go to the maintenance / router status and bottom off the page show statistics, all times should be the same but you can capture and post the page up just give it some time to fill in the data fields. You will need the password to logon when asked.

JimM1 — Sun, 27 Jul 2025 20:45:08 GMT

@Inbound8621 So what else was going on at the time when you had and there is NO doubt about it the NETWORK got real busy and just could not respond back to anything!

Re: Consistent latency issues

Inbound8621 — Sun, 27 Jul 2025 21:50:27 GMT

Literally the only things going on at the time in the house were my parents watching TV and me running that test from my PC. No kitchen appliances etc just TV and PC. I'll respond to the other comment regarding the hub once I'm back from work tomorrow, thank you for all the help so far 🙏
