I was doing alot of reading on the forums and came across some articles about how having IPS turned on will degrade the network performance, so I wanted to test this on my network, I've found that if I keep IPS on, everything seems to work just fine.

However if I disable IPS within 2-3 days the router will stop functioning.

My internet connection becomes sporadic at first then stops functioning completely a couple hours after the initial outage.

When this occurs I can't even reach the administrative webpage on the device, I have to power cycle it to restore connectivity, if I leave IPS off, repeat scenario, after 2-3 days it'll lock up again.

If I turn the IPS back on, everything functions fine for days... weeks... months...

Is anyone else seeing this?

other than the obvious leave IPS on, any thoughts?

I'm pretty sure there is a problem here, I just dont know if i'm the only one experiencing this, or if this is a known bug of some kind.

I'm not sure if I should be upset or disappointed in the lack of interest of this issue with CISCO's Q/A or  Engineering department.

I assure you that I am upset. Why should we be paying a premium price for products tht just plain don't work as advertised. At least IBM has the decency to change the documentation when they can't make a product perform to specifications.

Of more interest is that my router has now been up for more than 48 hours without a reboot. This is the first time that has happened since I purchased it. I would like to update Cisco on this but I can't find out how to update my open case.

Thanks for being here Sam. It is somewhat comforting to know that I am not alone in this matter.

The only way that I am aware of is to contact the agent that was handling your case. I looked your case up in our system and will contact her for you with the update. The only other way is to make sure that when you talk with your agent to get an email if one is not provided.

Thank you. I appreciate it.

Hi Michael,

I am going to speak to the engineer who has this case assigned to them.  I would like to gather the logs and a config file.


From there I would like to get your case escalated to our Engineering team.

My sincerest apologies this has gone on this long.

Thanks!

On Thursday, second level support sent me some firmware to try. This seems to have resolved my issue. I have no more information on this firmware than it bears the release number 2.0.1.3. My guess is that it is not production ready at this point but that is ONLY a guess. My router has not had to be power cycled since I installed the new firmware.

Michael,

Thanks for the update

Are you able to post the firmware they provided you? I would like to try it and see if it resolves my problems as well

Not that I'm one to argue, but what is CISCO doing... what happened to firmware versions

v2.0.0.9

v2.0.1.0

v2.0.1.1

v2.0.1.2

For that matter where is v2.0.1.3 posted, maybe it is a beta release, I wouldn't know as it appears CISCO doesn't post firmware updates, but if what you say is true it appears to be more stable than their current production standards

I wonder what the response would be if asked about an IPS Update...

I am very hesitant to post something that Cisco has not authorized when I know so little about it. I tried to find your Email address on the weekend to see if you would be interested in trying the firmware but I only found out where you live and work. If we can find a way to exchange Email addresses in a less public forumn I would be willing to send it to you privately with ABSOLUTELY NO GUARENTEES WHATSOEVER and a USE AT YOUR OWN RISK disclaimer.

Hi Samuel,

What I would suggest you do is call into the Small Business support center at 1-866-606-1866 and open a case. Please refer to this thread.

A case can then be created and escalated to gather that firmware for you.


Thanks!

Hi all,

I'm experiencing exactly the same issue on my two WRVS4400N routers. I've tried firmware upgrade to 2.0.0.8 and problem's still there.

Since I am a french customer, who can I contact to obtain and try 2.0.1.3 firmware ?

Best regards,

Kévin

The following link has the support center numbers listed by country. You can call the number for your country and get assitance with downloading

the correct firmware for the device.

THANKS

The 2.0.1.3 Firmware is still in a 'beta' release.

when you call in, insure that you have your product Serial Number.

It may be beta firmware but my router has not had any issues since I

installed it. I was told that it had not finished regression testing.

For me, at least, it is a great improvement over version 2.0.0.8.

Thank you for your advice ... I'll call the french support tomorrow with my 2 serial numbers.

I'll keep you informed of the potential end of the issue if I'm able to obtain the new fimware.
