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.
