Virgin Media Hub 3 , RT-AC68U Speed Loss

[linkmaster]

My setup


Virgin Media Hub 3 in modem only mode, Line is maxed at 352 Mbs

RT-AC68U running Merlin 384.8_2

PC running ethernet connection directly to the RT-AC68U

My issue (I'm hoping someone may have had this issue and know a setting I can change)

IF I run through the Router , the max speed I get is 195-204Mbs

IF I run directly connected to the Hub, using the same cable from my PC , I max out at 350-360Mbs.

Does anyone know of a setting in the firmware I can tweak to get my full speed going through the RT-AC68U?

The difference in speed is a huge drop.

turn on nat acceleration or turn off QoS and TrendMicro

As a side note, check in the Virgin Community forums to see if your SH3 has the firmware version that tries to reduce the impact of the Puma chipset issue that affects your connection. Particularly if you play online games.

Turned Nat acceleration to Auto and Trend Micro and QoS were already off , unfortunately no change.

just for testing/comparing, change your modem from bridge to router mode, reset 68U and configure in router-mode too (double NAT), in another test with AP mode.

Power cycle the router to make sure to change is effective. Then check the state of HW acceleration on the Tools page.

Turns out HW acceleration was being auto-toggled off because I had Per IP logging toggled on, switching it off and a re-boot did the trick..many thanks.
