Wireless slowdown after a few days on latest releases.
-
Good question. Top should give us a pretty good indication.
-
RC2 rebooted again 3 times within 20mins this morning; but, now it's been up for a few hours.
RELENG_1_SNAPSHOT-07-09-2006-embedded has been up for week+.I got this in the logs of RC2..
kernel: pid 277 (fsck_ufs), uid 0: exited on signal 8 (core dumped)
But, I also get the above message on the units that work great.
Does this indicate a need re-flash?
I also get this every now and then…
kernel: ath1: device timeout
Even though the wireless keeps functioning.Is there a shell command to monitor and always display the last few system log entries?
Thanks, -Pete

No, enable remote syslogging to a workstation. Use Kiwi's syslog daemon or something else to assist.
It almost sounds like a bad power supply to me, but it's hard to say, really.
-
Or maybe heat? are the units placed somwehere in the direct sunlight and/or it's more hot as it is summer?
-
Thanks for suggestions to check.
It just started slowing again after running fine for ~5-6hrs, and I got this odd kernel message in the log (fyi, time is off)…Aug 10 03:14:35 dnsmasq[1037]: DHCPACK(ath1) 10.130.1.101 00:e0:98:e3:4f:e1 D7YMYK11

It doesn't appear that anything has changed in "top" from when it was fast; sometimes "system" goes up to 40% but not for long…

Any idea what rix is? Never heard of that..

It seems to run fast for ~5-8 hours, then gets sluggish for a few more hours, then reboots after that, like clockwork.
Here is, presumably, a last "top" before it rebooted; It appears ok…last pid: 58198; load averages: 0.08, 0.07, 0.07 up 0+14:26:31 17:55:56

There is no difference FreeBSD wise.... Nothing has changed except pfSense code which would not be causing this.
Ok. I the only other difference I could think of is this unit has two Atheros based cards in it, all other production units have just one. I've tested both cards individually, and they do both function for days. However, you'll find this second card is likely unprecedented...

It could be these two mini-pci wireless cards combined are generating too much heat.
One is 400mW 2.4ghz, and the other is 700mW 900mhz card. Although, after rebooting
it does run smooth and fast again for ~5-8 more hours.Thank you for the help, -Pete

That was my other thought, are the power supplies up to snuff'.

are the power supplies up to snuff.If it's power, would turning down the wireless tx Power in the gui help?
Here are the PoE specs:

[update]
I disabled Opt1 (the 900mhz card) interface, and it's been running smooth for 24hrs.
Next, I'll try a the same setup on different hardware, then I may resort 1 card per wrap. -
uhm ,normally the cards use more power on lower speeds, and turning down power might mean lower speed.
So basically you could be shooting yourself by doing that.SR-9 spec:
Current Consumption @3.3V
Transmit
1-24 Mbps 1000mA, +/-100mA
36 Mbps 900mA, +/-100mA
48 Mbps 850mA, +/-100mA
54 Mbps 800mA, +/-100mAReceive 400mA, +/-50mA
This is similar for most wireless cards, however the SR-9 consumes a lot of power.
-
total output of wrap with two wireless cards is about 22w
8watts real power from one atheros card
so if your usinf 400mw cards then you will be morealso make sure your bios is up to daye this can cause issues with minipci bus and atheroes cards

Even today, when AR5004x begins to be EOL, I still think cards like CM9 are the way to go. It's a shame that Atheros stop production of this wonderfull chipsets in flavour of the cheap AR5006x. I know i'll miss CM9 a lot…
