in the ground floor of our house i have a 2.4G router connected to the internet. to use internet all over the house i have the following setup in the second floor: 1x AC66U: 2.4G in WET mode, connected to the ground floor router 5G in AP mode 1x E1200V2: 2.4G in AP mode i bridged the ac66u to one vlan that only accesses port1. this port is then connected by wire to the e1200's wan port (because i need to separate the nets and need a firewall inbetween). one ethernet port of the e1200 is then connected back to port4 of the ac66u. this port is on a separate wan that is bridged to the 5G wifi. if you wonder why i don't use the e1200 in sta mode as a client and feed this to the ac66u's wan port, this is because its wifi coverage is really bad compared to the ac66u. i would like to run the ac66u in sta mode but it is broken and i did not manage to fix it (although i did a lot of test and i am pretty sure that either the in driver supplicant is misconfigured or broken). the strange thing is the following: if i connect a client to the e1200's ap i get low speeds (lower than 2Mbit) if i connect the same client to the ac66u's ap i get speeds that are about four times higher (about 8Mbit) i wonder how this can be as the packages have to travel trough the e1200 bridge to the ac66u. anny ideas what's going on?
