Re: ROS v6 Suggestions

I would love to see Winbox support more than just CHAP protocol when authenticating winbox logins to Radius. I would really like to see it support MS-CHAP or PAP specifically. We use encrypted LDAP backend and it only supports PAP or ntlm_auth challenge tokens, which excludes CHAP. Makes it very an...

Re: Low throughput of small packets

They just get ~8 Mbps with 64 bytes framesize.

The rbs bridge the traffic. Connection tracking is turned off and no other special services are on.

Low throughput of small packets

Hi forum, one of our customers needs a 20Mbps full-duplex point to point link, in this case nstreme2 (Dual Nstreme) is the way to go. Therefore we use two 433AH rbs with four AR5006X 802.11abg cards and four antennas. Antenna Type: Airwin 19 dB (5100 - 5900 MHz) Horizontal The link is very good: Rx ...

mtu size testing

Hi,

Is it possible to test the mtu-size without fragmenting the packets?
In Linux it looks like this:
ping 192.168.1.1 -s 1492 -M do
I made a custom probetype with 1500 bytes packet size, but I think that these packets are fragmented.

thx,

Hello,

Try to reinstall RouterOS with netinstall and see if it helps.

Hi Smith,

the problem is that all wlan-accesspoints in our environment are configured as bridge, routing is done by cisco-routers.

Bridge is not the only way to make it work. Try routing, shaping will work, trust me...
does that mean that queues only work in routing-mode?

If I connect via ftp to the MT, the root dir contains the directory "hotspot" - nothing else should I upload the whole *.npk files in the root directory and reboot?
