RouterOS v2.9.45 implemented a new hw-retries setting for wireless cards, but I cannot find a status on how many have actually occured. I believe it would be of use to be able to see a total number of hw-retries, and/or the number of hw-retries that the last trasmission required.
Is there a way to view this info in either Winbox or console, or is this not possible in RouterOS?
Cheers
Hi,
Maybe looking at a specific entry in the access-list, then under ‘statistics’ you could get some sort of idea on the amount of tx-frames compared to hw-tx-frames and get some sort of idea on the amount of retires.
I haven’t done much research on this, however someone recommended 7 retries after he randomly picked it. I’ve done the same, ccq has gone from 40% to 70% by that change alone. Even on good links where the ccq is 80-90%, it will nearly peg it at 99%.
Isn’t the default 15, which is the highest? I don’t see how lowering it would improve quality, unless it counts failed transmissions as “successful” after reaching hw-retries.
Could it be that a poor connection is trying 15 times which is taking away from the timeslots for other connections and by lowering it to 7, the CCQ for everyone else goes up?
My shot was point to point, no other clients. Made a big difference. When I had interference, the pings were erratic, 6ms, 150ms, 14ms, 600ms, 65ms, 6ms, etc…
Afterwards, ping never went over 200ms unless I was seriously hammering on the link during interference.
Is this a setting that only needs to be set on the AP or should it be set on clients as well?
When I set it on the client side (my side, I could get to it if something went wrong), ccq went up on the rx side of the ap. When I did both, the difference was signifigant.
Hmm, what about for non-mikrotik clients. Like a laptop connecting or something running DD-WRT. I have a number of these devices on my network and I am wondering if there is anyway to apply the settings to them.
From what I’ve read on the forum, take it or leave it, standard 802.11g is 7 retries. MT uses 15 by default. Dunno why yet.
When installing a new wireless card on 3.0rc13 it sets the hw-retries to 4 by default. 15 only seems to be set when upgrading from an older version..
