still problem with bandwidth...

RouterOS General
1

hi

I have still problem with bandwitch:

side one
mt 2.9 rc6
routerboard 532 with Senao Atheros 5212
wds and bridged interface
22 dbi anthena

side two
mt 2.8.28
pc (via, athlon xp 2400) with Senao Atheros 5212
wds and bridge
22 dbi anthena

ok in 802.11 b all works fine
but in a/g this same problems :
from side one only 1 mbit
from side two ok (20 - 30 Mbit)

tested THROUGH the router
tested via ftp,

i mailed support, but answers are not good

I think there is a problem with mt athreos and routerboard

signals:
802.11 b -58
802.11 g -60
802.11 a -64
ccq 20 -50 %

I changed everything cards, anthenas, connectors and still problems in a/g

maybe in future mt will fix this :slight_smile:

config of cards :

i only change band

Maybe someone can help , maybe not

i checked manual, forum … and nothing

I see that side two seems to work well, while side one does not. Have you determined if the problem with side one follows the OS version, or if it is because the Routerboard is a slower platform? In other words, does the PC-based router show the same problems as the Routerboard router when you upgrade it to 2.9rc6?

Also, you should rerun your tests, this time having manually configured the data-rates on both ends to one single common value, such as 48Mbps or 54Mbps… Make sure that you have only one data-rate selected for the test, because RouterOS has been known to severely decrease usable throughput when it is trying to auto-select the data-rate in real time while data is being transferred…

i set 48 or 54 and still problem
