This is the second time this has happened. The wireless interface (Atheros 5213) has disappeared after the router has been running for a few days. I’ll take a supout again, however all these bug reports and no response makes me wonder if its even worth it.
I have been running RC4 and AR5213 for a since
RC4 came out. I have not “lost” the interface once.
It has been stable as a rock (Low traffic use, 5 to 10 clients)
This has happened to me twice on two different RB532s with two different Atheros cards. It actually had me mark the first Atheros card bad, before I had it happen a second time. The second time this happened, I tried the card in another RB, and it worked. A second Atheros card then worked in the original failing RB532. After discovering the problem was resolvable with the second Atheros card, I tried the first one that I had marked bad, and it worked just fine… I’m still waiting for a fix, as it would be nearly impossible for me to have this happen twice by accident, have it happen to you by accident also, and not have it obviously show up under thorough manufacturer testing(or are we solely counted on for that?)…
Is this specifically an RB532 + atheros problem?
I am running various (different) boards, with CM-6, EM-9 and CM-9s, with RC 4, no problems, in extended soak test, and live traffic applications.
I don’t have an RB532 to test.
This is on an Intel 815 board that we’ve used reliably/flawlessly for the past 1-2 years on 2.7-2.8. Dlink card with the Atheros 5213 chipset. It’s only happened 2 times so far, and only since upgrading to 2.9. I wonder if it has anything to do with doing an upgrade from 2.8->2.9. The other install (same hardware & card) hasn’t had this happen (clean install), although its a test machine and gets no traffic unless we’re testing things.
Not sure if this is still out there but we are having the same problem, all they way up through RC7. Using RB513 Routerboard running RC7. The wireless interfaces just disappear with the only resolution being re-seating the wireless cards. Unfortunently, this isn’t a viable option with disperse remote 140+ ft tower sites.
Obviously, this is not an upgrade issues as RB513/532’s only run 2.9.
Has someone acknowledged this problem? This doesn’t happen to all of our boards. All of our boards use Atheros Cards (CM-9, SuperRange2/5)
Actually, we haven’t used CM-9 cards in the RB513’s. We have only used the SR2/5 card and what I realized is we only seem to have the problem when the SR5 (5.8ghz) card is used. We originally though it was because we were using two SR2/5 cards, so we quit doing that. Well, the current problem we are having only includes 1 RB513 and 1 SR5 card, which threw our original idea out the window.
Does anyone have any insight? I don’t think it is coincidence or bad boards (as too many people have had this problem). It’s not an upgrade issues (as our boards have only had 2.9 on them). It’s not a two-card in one box issue (as I noted we now have them problem with a unit with only 1 card). Any other ideas? We do have the board set to 333mhz. Did others with the same problem have the boards set to 333/400mhz?
Sometimes it is, sometimes it isn’t… Also, all of the boards I have had this problem with were using only one CM9 at a time. I have also run dual SR5s in RB5xx turned all the way up, with no problems… I have one board now that started behaving exactly as this topic’s title states, but has gotten worse to the extent that the top slot no longer works at all… I now use the board on my test bench, and have the CM9 in the bottom slot. I noticed that the newer RB511s used a black Mini-PCI socket instead of the white one I was used to, so maybe there was a problem with a batch of Mini-PCI sockets???
As noted, power-cycling the radio sometimes fixes the problem, sometimes it does not. The only sure solution is reseating the wireless cards. Even some times this takes two tries. I myself have not experienced this problem with CM-9 cards, but we haven’t really used CM-9’s in RB532/513’s with RouterOS2.9.
Also, in case anyone was going to ask, we use 24v power supplies providing 24v 1.25A.
The only common occurance I can see with all of our problems is the OS. Im pretty sure this is a bug, but can’t confirm. I have opened a case with MT support, will update everyone if I hear something.
John:
Usually I would listen to your advice, but the problem I am having right now is that the wireless interface is disappearing with only one installed SR5 card. The board is set to 333. Any other ideas?
Thanks everyone so far for your help. 36 hours and I still have not heard from MT support…
Is this whole problem a 333MHz “overclocking” issue ?
Does sound a bit like could be PCI bus timing stability at that speed.
Am about to order some of these cards for testing, would like to know also …
I made the topic post initially - this problem occurred on an intel 815 motherboard. I don’t think its related to the RB, or else we have 2 problems we are trying to track down. If reseating the cards changes things then its a hardware problem. If it’s mainly the reboot during the reseat that fixed it then we might have something in common.
Test what exactly?!? My process of elimination, we have all eliminated a lot of things. We confirmed this issue isn’t specific to the SR2/5 cards as some expierenced this with CM-9 cards. We also confirmed this issue took place on both 513 boards and 532’s. We also confirmed that overclocking is not an issue, and I have confirmed it has nothing to do with running two cards at the same time. Some one else also mentioned this happened on an intel board. The only thing left is the OS, and MT support pretty much just tells me the mini PCI card is broken and thats it…piss poor help in my regard.
