TomatoUSB

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.

I flashed Shibby's latest… no change.

Is this a hardware issue?? My laptop wifi cards (also tried an ALFA) should be able to pull more than this.

Intel wifi is crappy and that's your problem.

Im seeing the same issue when I upgrade my firmware to Tomato Firmware v1.28.9054 MIPSR2-beta K26 USB vpn3.6.
Wont go past 20mbps for download and I know I have 30+mpbs download and 6mbps upload with Comcast.

Intel wifi is crappy and that's your problem.

Um… no.

I get the same issue using an Alfa AWUS036NH
