RouterOS v2.9.45 is out. We have implemented a fix for the wireless problems that arise recently in the forum about the reconnection of the clients. For all those who have this issue please upgrade to v2.9.45 and check the results. We added a new setting for hardware frame retries (hw-retries), by default it is ‘15’. If you experience problems in your wireless network you can try to set this number to ‘4’. Also we recommend for those clients that have this wireless client reconnect issue to set the ‘preamble-mode=long’ and ‘hide-ssid=yes’
What’s new in 2.9.45:
*) routing-test -
fixed memory leak;
inside confederations ignore routes with our AS number in AS path,
this fixes looping of routing information inside confederation;
*) calea server supports limited intercept;
*) mac address changing did not work for RB44G (realtek 8169 chip);
*) fixed bug - could not set new-tos in mangle rules from console;
*) realtek 8169 ethernet chip (rb44g) could stop when using vlans
*) user manager - fixed bug for PayPal payments with user data containing
specific characters;
*) implement hw-retries setting for wireless;
Can you provide a bit of a description as to what the “Hardware Retries” feature does? I have a few devices that hopefully will benefit from this fix, and I would just like to understand a bit more about what is actually happening with it.
yes, oh.... my god !!!
I used it parameters, and after upgrade to v2....45, why my wirelessly [RB511s] encrease the signal from clients and more stable. and upgraded x86[centralized aaa] too, i don't have any problems.

2.9.45 is a great update. I was able to work around the previous wireless problems, but the new .45 code came right up and connected with all my sites instantly (prims and atheros).
I they tambem I wanted to know more regarding the “Hardware Retries”…

BTW I upgraded a few of my links today, when you upgrade upon reboot the wireless cards were disabled. Just a warning to those that want to upgrade without being on site.
Hello again...
just put report image, coz i am very happy, and before i never have like this:
i put hw-retries=7 and normally all my clients not more than 3 hours have associated with central ap, now you can see uptime is more than before.
We have already dropped SR2’s from our network and put 8602+'s in due to the association problem, So far 4 towers upgraded and running better than ever. No association problems when changing the interface, and is it just me or is the signal strength 1000x better?
Example, a client with dynamic ACK 200 did report -85/-88 signal at 2Mb/s. NOW after upgrading to 2.9.45 the same client now reports -76/-80 ROCK SOLID!! this example is system wide across all of our clients on atheros driven MT towers now running 2.9.45
Fantastic, after this upgade I (so far) have no association problems, I’ve (after succesfull reboot!) set the pre-amble to long, but due to law in our country, I cannot set hideSSID=true…
But every time I rebooted one tower, had problem, so far, so good. I’m very happy, thanks MT!
Now after a day, I start to get more problems that before…
4 of my uplinks between towers lose connection. Sometimes it is connected but I cannot ping it, other times it just would not connect. Signal is good and they never gave problems before 2.45…
Every few minutes a link goes down and after 10 minutes or so it comes back on again. What is also strange is that for a few seconds, I can ping some router beyond the link that is down, but not the router itself, then a second or so later that is also down. Also sometimes pinging from Dude, I get ‘ICMP errors’ in the ping.
???
HELP!
Ekkas
WOOOHOOOOO! Great stuff MT! Thanks for this great fix.
