EX3700 not supporting 802.11n at all allthough promised in the datasheet
Although stated in the datasheet that the EX3700 is supporting • IEEE® 802.11 b/g/n 2,4 GHz • IEEE® 802.11 a/n/ac 5 GHz in reality EX3700 get's no connection to 802.11n WLANs (tested with differen...

in reality EX3700 get's no connection to 802.11n WLANs (tested with different routers) neither on 2,4 GHz nor at 5 GHz.
Well, EX3700 (V1.0.0.76_1.0.49) we see link rates of 144 Mb/s, 270 Mb/s, and under ideal conditions (more lab-like, not really extending the WiFi much) even 300 Mb/s link rates on 2.4 GHz - what is clealry 802.11n on this band (802.11g would top to just 54 Mb/s).

Interface 802.11ac, 802.11a, 802.11g, 802.11b
So no 802.11n.
Weak documentation only ... the Factory Default Settings (p.46) list Operating mode 802.11a/b/g/n/ac. We could argue the Data Rates shown are just reflecting the maximum numbers for the various standards - Data rate in the 2.4 GHz band 54/145/300 Mbps, Data rate in the 5 GHz band 54/145/300/433 Mbps ... there are many more data rates possibe, depending on the signal, the conction quality, bandwidth, ...

Thanks you're right.
But the problem was primarily not the link rate but to connect at all to a WLAN in n mode.
Now it worked.
I could connect with g mode at 54 Mb/s to the WLAN with 100% singnal quality.
After I tried from the very same place to connect to the same WLAN but now in n mode and also 100% singal quality and it did not connect.
The solution was to put the extender literally in front of the router.
The singal quality also showed 100% (of course how could it be more than 100% ...) but now it connected to the WLAN in n mode (depending on the setup at 144 or 300 Mb/s). This worked with the Cisco and the AVM router. Still it not connects to the Zyxel router but it's not interesting anymore to investigate further.
Now after having finshed sussessfully the connection to the n WLAN I put the extender back to the place where it should extend the network (of couse not directly next to the router ...).
So back at the desired position the singnal quality is still at 100% but the connection of the extender to the router most of the time can not be established in n mode.
Only from time to time it works for a few minutes.
So bottom line if I want to use the extender at that position I would need to accept the 54Mb/s in g mode to get a stable connection.
Finally I plugged a long ethernet cable and use it now in AP mode ...
And yes weak documentation ...
