Some time ago I mentioned I have strange behavior of my hostapd.
I tried on both Wireless USB cards: TL-WN422G V2 and now RT5370 ( Bus 001
Device 002: ID 148f:5370 Ralink Technology, Corp. RT5370 Wireless Adapter ).
And result is always the same: speed 5 Mbit via WiFi (hostapd) while
Internet speed via cable directly is 14 Mbit.
USB card is connected to terminal via 2m USB cable.
Terminal: HP Compaq t5730w Thin Client - Hewlett-Packard
OS: Ubuntu 14.04 LTS, 3.13.0-24-generic
hostapd: 1:2.1-0ubuntu1 i386
I was informed it is not possible to have hostapd on internet speed
influence. Hostapd is not involved into flow of packets.
Is it valid and correct ?
Best regards
Mariusz
