RVS 4000 Drops LAN devices

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

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.

RVS 4000 HTTP mgmt interface hangs @ Port 80 & DHCP stops working

This is the RVS 4000
Firmware version 1.3.3.5
STAR 9202 Chipset
64 MB DRAM
8MB Flash
DOS, Block WAN Rq, Remote mgmt all OFF
IPSec Tunnel none used
Internet connection is DHCP
LAN is set to DHCP with several Static devices defined
DMZ is dsabled
Functionining as a gateway
Time is set via NTP & the NRC
IPV4 Only
Everything is pretty much dedault except for QoS
Trust mode is Port, set to 4, 4, 4, 1
( Port 4 has a Linksys ATA plugged into it for VOIP services )
SIP Port Forwarding is enabled for 5060
Every day or so the Router becomes unresponsive to the HTTP mgmt interface, as well as it no longer offers DHCP services.
When this happens the only remedy is to power reboot.
Everthing comes back online just fine, however, the LOGS are initilaized so no data to figure out what`s going on.
My next step is to setuo a syslog server and have the logs copied out.
Anyone see this kind of behavior before ?
Any ideas ??
( No, I have no Torrents running at all, but I do have several devices like AppleTV, PS3s etc that run streaming Video plus I have the SPA3102 )
Thanks Derek

Hi there Vijay !
I cannot upgrade to that version of Firmware as my RVS4000 is a V1, not a V2.
Is there some way I can change it such that it will load the newer Firmware ?
This is the error I receive when trying to upgrade anyway :
"Upgrade file is not the correct type or version for this device.
Upgrade failed.
Please obtain the correct file and try again."
Otherwise the newest firmware I can load is 1.3.3.5
( which seems to have this problem )

No Internet Access with Static IP and RVS 4000

I have an RVS 4000. I have several PC's to which I have assigned static IP addresses. I have recently upgraded most of the PC's to Win 7 (64) machines. I updated the firmware on the RVS4000 to 1.3.3.5 in conjunction with this. After such update (and actually before as well) I could not assign a static IP address to a PC and have access to the internet. It connects fine to my LAN, just no internet access. This is also affected on several other machines running Win XP and Win 2003 Server, so it's not just this computer.
I have:
     1. Shut down (powered off/unplugged) everything, router, DSL modem, switches, server, etc.
     2. As I said firmware is current.
     3. Yes, DNS servers and gateway, subnet, etc. are all correctly specified on the PC.
     4. Router is set for gateway mode.
     5. Set to only IPV4.
The only way it allows internet access is to use DHCP. I've even tried taking the IP address via DHCP and manually assigning the DNS servers and that works fine, but as soon as I assign a static IP internet access is immediately gone.
There must be something I'm missing, but I can't seem to find it.
Everything worked fine prior to the conversion of the Win 7 machines, i.e. I had several PC's with static IP's and no problems.
Any thoughts appreciated.

As an addendum, if I turn off the Firewall (internet access policy to disable) it will allow the static IP computer to have internet access. I have the DHCP range set to be .5 - .54 and am using a static ip outside this range. The Internet access policy is to restrict those PC's getting IP via DHCP.

Yes, I posted this same information in the Video Surveillance section a few weeks ago. it was actually a Partner on the
community who found this and brought it to our attention and we fixed it.
Thanks for cross posting here, since you are right in it also effected this router.
And a big thank you for taking the time to collaborate some very useful information with the community. I have noticed your recent posts and I think they are well writen, helpful, and well organized. I also like your idea of turning some threads into solutions documents and resource labs perhaps.
If you would ever like to post something of that natire, you may also. Just creat a document with your findings.

RVS 4000 Email responses that need addressing

I have been bounced around between Cisco and Linksys for months….
I have two simple questions… One I know the answer on… the second, I haven’t a clue…
I have corresponded with 12-15 people at Linksys, and Cisco…
Their last answer is I should contact you…. So… Here goes…. The 16th person I’m requesting this information from….. (I can’t believe that Linksys/Cisco can’t answer these simple questions!)
Seeing that I've been checking for new firmware and IPS downloads from the Cisco site for months now, and not seeing any new downloads......
And Seeing that I'm getting nagging emails that my IPS Signature is too old, Please Update it!!!!
And Seeing that I'm still getting emails that I don't understand from the RVS 4000: -IPSEC EVENT: KLIPS device ipsec0 shut down
and I can't seem to understand How or Why it is happening, and have read manual cover to cover, and all the FAQ's, and can't upgrade it because there is no current software......
I sent the following email to [email protected] :
Hello. Have an RVS4000 Router, being used as a Gateway...
I have emails enabled, so that I'll be informed whenever there is greater than a set level of threats.... However...
If I check the logs, there are no threats... Yet....
I keep getting the following emails:
Your Signature Version is beyond 143 days. Please Update it!
I've also been getting the following emails:
-IPSEC EVENT: KLIPS device ipsec0 shut down
I'm using V1.40 IPS signature, and V1.2.11 firmware....
Yet I keep getting these emails...
I can't update the IPS Signature Version if you don't provide it!!! And you aren't!
Secondly, WHAT THE HECK DOES: "-IPSEC EVENT: KLIPS device ipsec0 shut down" MEAN????
May I suggest that the next version of firmware have options to disable the IPS "Nags" if you are not planning on writing any more code?
And, What the Heck does: "-IPSEC EVENT: KLIPS device ipsec0 shut down" mean?
Sincerely

RVS 4000 on Port 587

hi
I just bought RVS 4000 a week ago. My previous router can send email through port 587,
Ever since i bought RVS 4000, it stop sending emails. I opened port 25 and I have tried all my best to do port forwarding to port 587 but still it cannot send email.
My ISP is using port 587.
Please help help me on this. What should i do to be able to send email on port 587?

Hi Lui,
When you say send mail on port 587, are you referring to sending mail from the LAN to the WAN on port 587? Or a port forward translation from 25 on the WAN to 587 on the LAN?
On the RVS4000, you can perform port translation by going to the Firewall Page, then Single Port Forwarding. Create an application name (text based, will not affect config) and then you can choose an external port to internal port. Lastly point to the internal IP address of the mail server.
If you are referring to sending mail on port 587, the router is by default going to allow all outbound traffic out and will not block or filter ports.
Please let me know if this resolves your issue.
Thanks!
Dave

RVS 4000 DDOS Attacks

Hello!
Since I got a NAS System connected to my Network (one Month ago) I get attacked every day by DDOS attacks.
I Just set my NAS to the DMZ of my Router and opened 3 Ports for Service of QNAP.
I assume that at this moment I got scanned and thererfore the intrusions started.
For the last month I experianced nearly every Day Internet Connection Problems and the Router didn't respond anymore.
As I found last week a new Firmwar-Version I updated my router, enabled IPS and applied the latest Security file.
In the IPS Report I found loads of DDOS and Synflood attacks.
With IPS my Router Works and I got no more problems that my Inet access is corrupted BUT now I got the Problem that my
downloadrate sunk to 20Mbit from formerly 100Mbit.
I already wrote my ISP about this situation and want them to change my WAN-IP Adress but they to it only in very urgent cases.
Is there any option to operate the RVS 4000 save AND fast???

Sorry I seem to have no access to the documentation,
I get:

Oracle lite Java Command to drop a device

I want to know if there is a java method to drop a device from the Oracle lite repository. I don't find it in the java doc. If such method does not exist maybe I could delete the Device in the repository tables? Is someone did that before?
Thank you
Simon

is that what you need?

3.1 Deleting a Client Device
If you want to delete a device, use the delete method from the Device class. To retrieve the Device object, use either the getDevice or getDeviceByName methods, as demonstrated below.
If the device id is available, the following can be directly used:
if (oracle.lite.resource.ResourceManager.getInstance() == null)
oracle.lite.resource.ResourceManager.initialize(JDBC_URL, USER, PASSWORD);
oracle.lite.resource.Device d =
oracle.lite.resource.ResourceManager.getInstance().getDevice(deviceId);
d.delete();
If the device id is not available, then you can provide the device name, which is shown on the Mobile Manager UI in the oracle.lite.resource.User.getDeviceByName(deviceName) method. Once retrieved, use the delete method of the Device object as demonstrated above.

RVS 4000-V2: PPPoE failed - "unrecognized option '1492'

I've got a brand new RVS 4000-V2 router (firmware: Release 2.0.0.3)
Can't get a connection to my ISP using "Internet Connection Type" PPPoE.   The connection works fine with any other router.
MTU size is set to "auto".
Logfile says:
Plugin pppoe loaded
PPPoE Plugin Initialized
Plugin pppoe called.
unrecognized option '1492'
I use the standard Web-administration client.
Any ideas?

Thanks
for the reply.
In the meanwhile I've tried it with another DSL-Modem - same effect: No connect to the Internet-Provided
,    "unregognized option '1492'" in den Log-File.
I have no problems with the Internet Connection using a differend router from another brand with both of the modems (Siemens Plus or D-Link DSL 321B).
I have attached a screenshot of the WAN settings as requested.   I tried both the auto and the manual mode. No success.
If you give me directions how to trace the WAN Port with your router, I would do so.
Best regards

Connecting 3 RVS 4000 with VPN

Hello,
i want to connect in a triangle 3 RVS 4000 Router with VPN
i have configured 3 routers, which are able to connect to the Internet. Each of them are configured as a gateway.
i have created 2 tunnel on each router. But the vpn connection can't be established,
here is the configuration of router1 the other are configured in the same way, only the remote group setup is different
Do i have to open also some ports for the VPN , if yes which one and were
Thanks fpr your help and response
HP.Meyer

Hello,
Are you trying to ping the IP address of the clients behind the routers or the computer name? You will need to use the IP addresses only unless you add the names to the LMHOSTS file in your PCs. Also, if there is any antivirus or third party firewall software running on those clients it will block the PC from replying to pings from an untrusted subnet. For example you ping from R1 with 192.168.100.1 to a PC behind R2 that has 192.168.101.x. Because the antivirus or firewall software on the PC sees that the ping request is coming from a different subnet it will block the response. You will need to either disable any security software or add the untrusted subnet to the trusted list in that software. Sometimes it is best to test by pinging something that does not have any software, such as a printer or print server.
Please keep us updated.

I have an ipod and an iphone 3GS and a wireless LAN device, with my ipod I have a connection, but not with my iphone ... why is that?

I have an ipod and an iphone 3GS and a wireless LAN device, with my ipod I have a connection, but not with my iphone ... why is that?

- An iPod can only sync with one iTunes library. Yu can however manage music and videos among different computers by:
Using iPhone, iPad, or iPod with multiple computers
- To change syncing computer, move all the media to compute r#2
- Connect the iPod to #2 and make a backup by right clicking on the iPod under Devices in iTunes and select Back Up
- Restore the iPod from that backup
Note tha the iPod backup the iTunes makes does not include synced media like apps and music.

My system is a HP Envy 14 - 1240ep. I'm using BIOS F.23, I tried F.26, but the BIOS update didn't solve the problem.
I tried Disabling the BIOS option for LAN sleep mode, but that disn't solve it neither.
I have a clean install of Win7 Pro 64-bits, and tried to install the original SwSetup NIC dirvers (however, since I've got the error for unplugged cable, I'm not sure if everything went ok).
My NIC is in "comma" for 2 weeks now. During the past 2-3 months it would work sometimes after the cable was plugged in for 3-4 hours. In spite of turning on it would go off after any stand-by, restart or shutdown.
I'm starting to get empty of ideas to crack this problem.
Any suggestion?

New Quantum Gateway G1100 Prohibited LAN devices?

Hi I just received a new Quantum Gateway for FiOS TV and Internet, the LAN ports on the device are covered with a sticker prohibiting other than consumer electronics to be used. What devices are the einsteins at FiOS refering to? Are they trying to prevent attaching ethernet switches to expand the number of LAN ports? Has Verizon disabled NAT functionality?
Anybody know what Verizon is up to?
Solved!
Go to Solution.

Probably there to provide legal cover if somebody plugs in a medical device or some other mission critical thing.
NAT is a must for these routers; don' t know why you'd assume it wasn't there. WIthout it, they would be worthless.
Switches are fine. Many folks, myself include, expand our wired networks using switches.
As long as you aren't running a trauma unit or a nuclear power plant, ignore the label. The G1110 is a very good router. Use it and enjoy it.
Enjoy.
