When I ping the IPv4 address of Janet’s iPhone from my iPad, both on the same WLAN, the ping times are mostly ~120 ms, occasionally 6 ms. Why so incredibly slow? Is it because my WAP is rubbish?
It’s an 11-year old ZyXEL business grade £300+ ZyXEL NWA 3560-N. I have three of them, two in use, one spare. Slow processor in it possibly, by today’s standards; iirc a MIPS 400MHz CPU. The web UI is noticeably sluggish at times anyway.

Do they perhaps need a regular reboot to clean up the RAM? Slow UI would certain suggest something is upsetting it.

Memory leak ? Alloc heaven ?
I think the web UI is always slow 100% of the time, including straight after boot, iirc. I don’t recall sometimes thinking that it’s better.
Is it possible that the WAP can’t cope with the encryption/decryption well ? If with a weedy CPU. Has that ever been heard of?
I haven’t found a detailed spec that included a mention of the CPU, it’s just that 400 MHz MIPS64 rings a bell.

Always slow I would expect for something like that, but "sluggish at times" is was made me wonder if something is pegging the CPU which would impact ping response too.

256MB RAM, 32MB FLASH according to Wiki Devi: https://wikidevi.wi-cat.ru/ZyXEL_NWA3560-N
Is one of the APs acting as the controller for both of the APs?

If you Google 'iphone ping times' you'll find many reports, some old some new, of inconsistent times like you are seeing.

No, I’ve set them up independently. With this model, if you set up one as a controller, as believe it won’t also work as an AP. I did have five APs and originally intended to dedicate one.
