Deco M5 : Speed is good except for one iPhone
I bought the M5 about 2 years ago and generally it's been ok...However we do have a problem in that when we do speed tests on our iPhones (family of four) three of us get about 38mbps, which is about right for our area. Unfortunately my son with his IPhone 11 was only getting about 3mbps on average.
He bought a new IPhone 12 today and on checking his speed, it was still about 2-3mbps...
Any Ideas?
Ive tried various things like rebooting, checking blacklist, switching between 2.4 and 5 ghz, switching to guest network etc
Its driving him nuts!!!
