I am using 1.28.7500 MIPSR2Toastman-RT K26 USB VPN on my Asus RT-N16 router.
No QoS or BW limiting set. Using Default Wireless configuration.
Connecting to multiple WLAN clients all exhibit the same symptoms….
Limited to ~20 Mbps down (uplink is fine at 10 Mbps)
I have confirmed ~50 Mbps down and ~10 Mpbs up when connected directly to the router using the Ethernet ports. This is the same as my provider allotment (Comcast)
But only ~20 Mbps down - ~10 Mpbs up when connected wirelessly.
RSSI Quality TX/RX Rate
-40 dBm 36 144/144
using a Intel(R) Centrino(R) Advanced-N 6230 with WPA2 AES encryption on a Win7 x64 laptop.
I have tried playing with some of the wireless configuration settings with no luck.
Tried WMM disable, a bit slower with it off.
Tried disabling WPA2-AES for open authentication.
I have tried other N-adapters too (ALFA) and on different Laptops too. Same limited downlink BW.
Distance from the router does not help either.
EDIT: Updated to 7502 (tomato-K26USB-1.28.7502MIPSR2Toastman-RT-VPN)…. no change.
