65Mbps is single (spatial) stream, 20Mhz width, Long GI
and I'd assume the number of spatial streams will be related to the number of antennas in both access point and laptop.
The poster could try short GI if an option on the AP and it may increase to 72Mbps
(not 75), If there are few neighbouring networks and few devices connecting that will probably be ok.
Although the poster could try to set "40Mhz" (double-width) or "Auto 20/40" not all devices are compatible and there will be interference unless the neighbour moved down to channel 5.
In this case the poster could stay on channel 13 and 40MHz would effectively be 13+9 (plus overlaps) leaving 1+5.
At work, we never
deploy 40Mhz in 2.4GHz unless there are no other networks in range and we don't worry about trying to eek out small gains from short GI because the band is already so congested so Long GI may mean less retransmits anyway.
In addition, if using encryption
the poster should use WPA2-AES
(CCMP) not WPA1 nor TKIP.
Wireless hardware acceleration is available for AES (via the chipsets or enhanced processor instruction sets) and may not achieve maximum rates on WEP or TKIP.
