Problem with AP 5.21 + NV2

Anyone else experiencing AP’s running NV2 that completely stop talking to the Client Radios ?

When this happens none of the Clients are reachable - ping, Mac Ping - fail. Power cycling the client does not resolve the problem. Disable/Enable the AP interface and everything starts working again :frowning:
Anyone ??

supout.rif sent to support

we would need more detailed info on your Nv2 network so we could try to reproduce it.
How often does it happen?
what usually triggers the lockup - upload/download or some bandwidth testing?

I have NV2 running on 8 AP’s now and 10 PtP links. NV2 Distance and Slots vary depending on the AP.

The problem appears to be completely random. It first happened on a PtP link only 13 hours after I installed 5.21 on those two RB’s. It has since happened to THAT PtP again, and another one as well.

All of the “AP’s” that have had the problem so far are running as a router, no bridging.

The most recent one (that I sent you the suppout.rif from) has 42 connected clients. Radius Auth. for Wireless. Radius DHCP. Nv2 Period=4, Cell Radius =10. No NV2 security. Card is an Atheros 5413. RB is a 433AH. Uptime since upgrade to 5.21 is ~4 days 7 hours. ALL on this AP clients are also 5.21.

You can email me at the address from ticket [Ticket#2012102366000597] if you need further info.

Thanks.

please try to lower the tdma-period-size to 2 on the AP and check again.
The AP and the Clients uses the legacy AR5413 chipet cards?
What wireless mode you use for the wireless clients: station, station-wds or station-bridge?

Period size on the point to points is already set at 1.

If I set the period to 2 on an AP with 42 clients it takes them a very long time to re-associate (5 or more minutes) if they drop :frowning:

Sorry posted too soon… All clients are Station mode. I’d say 90% of the customers are R52H. Remainder are R52Hn or RB Groove 2hn.

The same problem with my AP which you have remote access. [Ticket#2012062266000221]
The problem occurs randomly (even just once a week). No BW test running.

What type of Card do you have in the affected AP? Are you running the AP with B/G or G only ?

I’m having same problems on grooves and metals. Random reboots, disconnects and other crap like that. To make things even more fun, after /system package downgrade metal went bye-bye. Feels like 2.9 all over again :frowning:

This isn’t a reboot problem. The AP side just stops talking to the CPE’s. CPE’s are mostly R52H on RB411. I have probably 30 Grooves as CPE’s running 5.20 or 5.21 and no issues with them. No Groove AP’s though. Other than this issue 5.21 has been very stable - and latency and jitter are way better than previous versions of NV2.

Well, I replaced a groove after upgrading it to 5.21 with Metal. Now co-worker gets on the mast to replace metal with another metal. Either two devices were broken, or 5.21 is broken. I’m not planning on uploading 5.21 again. Metal is now confirmed dead after attempt to downgrade 5.21->5.20 - ethernet doesn’t even come up…

I have no metals - just the older style 2Hn grooves.

BTW: Isn’t the Metal just the mipsbe ?

I don’t understand your question.

The Metal is just the groove in a steal case is it not? The Groove is a mipsbe board. mipsbe is the platform for the RB4xx.

Yes, that’s correct. Not sure about any subtle hardware differences, but it’s mipsbe. Oh well, sent some supouts with wireless lockups, maybe it will get fixed along that :wink:

can one of you provide us remote access to such AP where the Nv2 stops working - needs disable/enable, as we can’t reproduce this problem locally?

About Metal downgrade from v5.21 to v5.20, what packages you used and what bios firmware version you had?

Done - please see your email for the ticket.

BTW: Yesterday overnight I tried setting the TDMA slots to 2, but could only authenticate ~24 CPE’s. The status Tab showed “Connected 42, Authenticated 24”. I cache radius responses for 2 minutes. Radius resends were low but the other ~18 CPE’s could not authenticate (?) In the end I could only lower the slots to 3 and still have all subs authenticate.

ULDIS:

It it currently broken. If you wan in you have 5 minutes before I reset it.

I sent TWO supout files via Email. Please advise if you think this problem would be resolved by replacing the b/g card with a b/g/n card ???
