RVS 4000 Drops LAN devices

[ashforma55]

I recently updated my network with the following:

RVS 4000 v1.3.2.0 - Linksys by Cisco version

SG200-26

AP541N [WAP]

All devices have the latest version of firmware.

Users only connect laptops via wireless, they are a mix of MAC and Windows users, devices such as printers and network storage are all wired connections.

The RVS 4000 would drop the internal Lan after several hours or sometimes days, there would be no reason to the periodicity it would retain and then drop the LAN. By dropping the Lan I mean:

Internet Access would cease, devices such as laptops would lose their wireless connection, a laptop requesting an IP address would be ignored. Effectively we were down.

Connecting a laptop to the network via a cable connection would eventually get an IP address but all other wired devices such as the NAS Storage and printers would be unreachable and require powering off and on to get an IP.

A reboot of the RVS 4000 by powering off the router would have to happen to restore the LAN quickly. I followed advice on the Internet and this forum by upgrading the firmware and resetting to factory defaults and then reloading the configuration.

The only change that seemed to make any sort of differnece was connecting the  AP541N directly to the RVS 4000 rather than the SG200-26. Throughput  increased and the period between LAN drops extended but the RVS 4000 would ciontinue dropping the LAN eventually.

When it dropped the LAN during a work day, that was it!

I read a lot of negative feedback on the version of RVS 4000 firmware and as the version 2.0 will not install I purchased the Cisco version of the RVS 4000 v 2.0.0.3.

The new RVS 4000 also drops the LAN! The period between drops is much longer, but it still drops the Lan.

Ventilation is good and it is sitting on its edge using the platsic feet that come in the package.

The AP541N is still directly connected to the RVS 4000 rather than the SG200-26.

Any ideas on how to fix the RVS 4000 or an alternative... I would like to stay with Cisco, an alternative, if the RVS 4000 is unfixable should have a browser based admin facility!

Thanks

RVS 4000 Firmware V2.0.2.7

IPS is disabled.

Gateway mode

I have little similiar problems. I lose browser and some of the LAN resources on but connection to WAN is functional. WAN functionality can be easily verified by making Skype call, mumble and online games are working. Cannot connect to RVS4000 but I can access my NAS from browser.

Anyone have help on this issue?

Mark,

Very strange behavior; it would seem with the earlier version and new version of the RVS4000.That this will be more an environmental issue. Now trying to find out what is causing this type of behavior. Need some logs from the router and the SG200 switch before any reboots. If you have the ability to set up a syslog server and capture this information would be great. Also detail information on what port each device is plugged into. Hopefully from this we can tell what might be happing in your network to cause this type of behavior.

Jarkko,

Your issue sounds like you have a default ip address conflict, this usually happens when you leave the default ip address of RVS4000 to 192.168.1.1 and many times modem are hard coded with a similar address of 192.168.1.1, which can cause the type of behavior I have seen the in past.

Also I would leave IPS enable unless you are trying to reach download speeds above 20Mbs

Thanks,

Hope this helps.

Hi Jasbryan,

I gaveup and return the router to the shop.

I can confirm that it was not IP address conflict since I moved the IP range away from default 192.168.1.1. I turned IPS off since the behaviour indicated that something is blocking part of the services. There was no any affect if IPS was tuned ON or OFF.

Mark, please consider making a call to the Small Business Support Center so they can work with you to quickly duplicate the issue in the labs with the router's configuration.
