Set up on Infiniy2 this morning & I am well impressed, hope it continues.
Couple of issues with HH4 however.
I'm trying to change the broadcast name from the default. Why BT insist on the same for both I don't know.
If I change the 5G band to Myname-5g then it does not show up as an available connection. Using WiFi analyzer, nothing shows up in 5G.
In the home hub manager it shows as ok but no devices connected.
I've reset to defaults and all ok again.
As an aside I assume that if both ID's are the same, any device will connect at the best speed. i.e. 5g will connect @ 5g & 2.5 @ 2.5.
did you try the ssid without the hyphen?
SSID's are defined to be unto 32 alphanumeric characters, so hyphens, underscore and other punctuation are not allowed.
Another one I am confused about, must be an age thing. How come the BT homehub ones start BTHomehub3-xxxx. If you can't use hyphens how to they use a hyphen after the BTHomehub3
There are always exceptions to any rule, the hyphen is probably the only punctuation character allowed.
The length of 32 characters has only been the limit since 2013, it was shorter, it has to be embedded in the MAC header block.
You would have to search in the 802.11 spec downloadable from standards.ieee.org for exact details. Several versions are available, including the 1999, 2007 and 2010 versions.
