Routers / Switches :: Losing Internet Connection And Stuff?

Sep 26, 2011

It is set to dummy mode so it should just pass through to the WRTG54S router which handles the DHCP.2) I have 6 computers sucking the internet off of the router. One is wireless.3) I have been set up for about 6 months this way. 4) I use to drop the DSL connection about twice a day. I would unplug the WRTG54S and plug it back in and everything would reset and work. Then, recently it has gone to about 15 times a dayThen, we have to make a major electrical change in the building, which required us to go to generator power only for 5 days. For 5 days, we never dropped the DSL connection a single time. Power was restored. Generator sent back home. Problem is back. Dropping DSL connection again.5) Hooked up APC battery backup power smoothing device to 3 cpus, WRTG54S, and DSL modem.

Routers / Switches :: Intermitted Internet Connection With New Motorola SurfBoard 6121?

Jun 15, 2012

Motorola Surfboard 6121, Every since Com-cast has updated their network (two months ago), my Internet connection is VERY unstable.Com-cast says it is my problem because I can get reliable service at high speed using just my laptop: Win 7, and the Motorola modem. The modem does show high speed connection (blue light) when the only thing connected is the laptop.If I connect the rest of the home network; ,LinkSys BEFSR11 router, Netgear FS #108 10/100 switch, then my laptop. The Surfboard modems light turns orange (lower connection speeds). do I need to replace my NetGear switch and my router? This constant up and down intermittent connection is terrible!

Cisco Switches :: Sf-300 48port Failing 802.1x Re-authentication?

May 11, 2011

I have an issue with the sf-300 switch model, which i am depolying in lapsafe trolleys. The approach is to wake the laptops from the guest VLAN (20) with WOL have them authenticate with 802.1x and use DVA to put the ports in VLAN14 so updates can be pushed to them over night.
I have configured 802.1x, guest vlan and DVA which works initially, all host wake from WOL, the laptops successfully authenticate and are assigned to the VLAN (14). This remains stable for a time then the hosts fail reauthentication. I have also noticed that when a host is disconnected from a port and patched into another port the initial port remains in the authenticated state and the new port authenticates the client but the hostnames are missing on the 'authenticated hosts' page of the GUI, DVA fails. The ports display a port-failure message for a time then moves to failed reauthentication.
The only way I can get it to work again is to reboot the box. From the logs I can see the macs of laptops being rejected and I can also see attribute 26 being ignored. See log below. I am unsure as to why host are initially authenticated but reauthentication fails, is it not the same process?.
I have 11 of these switches and have configured 6 which all display the same behaviour. These switches are not CISCO I do not understand why they have badged them. The protocols/standards are implemented differently. If you incuded 'general ports' as an answer in a CISCO exam you would fail. There are also other issues I have noticed with these boxes, I am not impressed!.

Cisco Switching/Routing :: 4510 PoE Switches Keep Failing

Jun 11, 2013

We have an issue where switches are failing weekly in a switch closet.  In the past month we have gone through several 3750G switches and a couple 4510s.  The power supplies have eventually made a popping noise and had to be replaced.  on the 4510s we've tried two chassis and gone through several power supplies.The switches have been behind UPS systems so should be receiving conditioned power.Could load from the PoE devices really be causing this?  I wouldn't think it's power since they are behind a UPS.

SFTP Connection Failing?

Dec 4, 2012

I set up a connection from a laptop (Windows 7) that goes through a LAN proxy server to a secure ftp server (Windows Server 2003).The sftp server is assigned a public ip address.I opened the firewall at the destination and allowed port 22 traffic to the sftp server. Well, the connection is failing.I know for a fact the connection from the client laptop is making it to the sftp server.If I issue this command on the client laptop:

telnet sftpserver 22

The DOS screen clears and tells me the type of SSH server I'm connecting to. While this connection is still active, I logged into the destination sftp server and did a netstat command. I can see the address of the proxy server in the "Foreign Address" column of the netstat results. I also can see the proxy server address when I look at the Application Log on the sftp server, so I know the connection is making it to the sftp server.

I beleive the problem is the control port (return traffic) from the server back to the client. Something is being blocked or is misconfigured. I always thought the router negotiated the control port, and that the control port didn't need to be put into any firewalls.

Cisco Routers :: Failing RV016 Or ISP?

Jan 22, 2010

I have a rv016 that's been in 24x7 operation since I bought it a few years back.  It is out of warranty.  It is connected to three cable modems on WANs 1-3.  Behind it are a bunch of PCs getting IPs via DHCP.  There is a gateway to gateway vpn tunnel setup on wan3 to a rv082 at another site.  There is a forwarding entry for http to an internal http server.  Everything else is pretty much default.
The router is primarily used to aggregate bandwidth for uploading large numbers of photos.  The systems behind the router initiate the uploads and the router automatically load balances the outgoing bandwidth.
This was all working fine until just recently.  The ISP is Knology who is upgrading each of the 8m/768k cable modems to 25m/5m.  They are also moving from DOCSIS 1 to DOCSIS 3.  They are currently in the middle of this upgrade and have upgraded the modems to DOCSIS 3 as well as the speeds to 12m/2m.  The problem is that the rv016 Network Service Detection, which is set to "Default Gateway" indicates that the modems fail randomly.  Usually only one will be failed, but up to two will fail the Network Service Detection simultaneously.
Knology insists that there is nothing wrong with their modems.  I have removed a modem from the rv016 when Network Service Detection indicates it is in a failed state and connected it directly to a computer.  It will work, but it has a different IP address and default gateway.  As soon as I connect it back to the rv016, it works there too, but on the original IP address and gateway.  I've only tried this test this twice so far, so it is a bit inconclusive.
Speed tests behind the rv016 are the same as directly connected to one of the cable modems.  The router works normally as it has for years.  Nothing else is acting funny.
So my question is, is the rv016 failing or is the ISP having problems?

Wired Network Connection Keeps Failing

Nov 6, 2012

To start off with, I own the network, and every system connected to it. I run and admin it, so the chances that anyone else has changed anything is essentially zero.This computer has a wired network connection (The issue) and a wireless one. They are connected to two separate networks. A few days ago the wired card stopped getting an IP address from my router, always ended up with a 169 address. Eventually I just disabled it, and installed a PCI network card.

Now what happens is that all works fine for a while, then stops. Suddenly I am "Not connected to network" despite the fact my ip address hasn't changed. I run the network troubleshooter, it tells me the "Gateway is unreachable" Resets the network card, and all is good. Then after a while the network fails again. I did already scan with malwarebytes, and everything is fine as fat as its concerned.

Cisco :: Identify The Point At Which A Connection Is Failing?

Jul 31, 2012

I've got an application running on a Windows 2008 server that I have verified as live on port 8085 at localhost. I've also verified on the server itself that port 8085(and in fact, all ports) are open right now. Despite this, I have no connection to this port on the server. Let me back up a bit an explain the architecture I'm working with.windows_server >> Switch >> Firewall >> Firewall >> InternetEverything but my server is managed by my hosting company who is insistent that this is a server issue. Is there a way to find out at what point my connection to port 8085 is failing? I feel like it's stopping at one of the Firewalls but need proof of this theory to get something done about it

Routers / Switches :: How To Connect Two Internet Routers To One LAN

Mar 8, 2011

How do i connect two internet routers to one IP address range?I currently have one broadband router connected on subnet, I have a second line which is a copper ethernet EFM 2Mb line connected using a Cisco 1800 router configured on subnet, no DHCP is configured on either router. the dhcp is provided by a windows 2003 server on our LAN which is also configured on the same LAN IP range. if i connect the Cisco router into the same switch as the broadband router my network devices stop working and dont respond.

If i check the broadband router it shows all the connections to it as having the same MAC address as the Cisco router?? if i disconnect the Cisco router everything returns back to normal and works perfectly.What I want to achieve is to be able to run both routers on the same LAN to provide internet access by configuring the pc's to route through a specific router. the DHCP I want to stay routed through my original broadband line. at the same time i want all pc's to access to the lan devices (ie. servers and printers) what the correct configuration would be for the two internet routers would be?

Routers / Switches :: Wireless And Wired Connection For The Same Set Of PCs?

Feb 1, 2012

I have 3 PCs (win7-64) connected to a wired gigabit network to achieve fast transfer of large files. Separately, at a distance, I have a modem-router to access the Internet. Internet access for the 3 PCs is achieved with each PC connected wireless to the latter modem router. The 2 networks are running OK and PCs can connect each other on both networks. Question: How can I know and achieve that the gigabit network is used for file transfers and not the slower wireless network? How should configure both routers and PCs to achieve this? I don't need the wireless setup to be a network, just to provide wireless access for each PC and that's it. I used to have the gigabit LAN configured with a Dlink DAP1522 bridge that created a single wireless connection between this wired LAn and the modem-router but it stopped working and I'm pretty done with it.

Cisco Firewall :: Connection Failing Intermittently - ASA 5520 Version 8.3 (1)

Oct 19, 2011

I have a server in a DMZ behind the ASA, connections to this server work sometimes and then fail others, so I dont think i'm looking at an ACL or NAT problem here.The syslogs report a SYN Timeout,I have taken a trace on the ASA, it seems that a SYN-ACK does come from the destination server within the 30sec timeout, but its not passed through the ASA back to the source ?  there is one odd thing, what seems to be an out of sequence ACK from the destination which arrives before the SYN-ACK at the ASA, i'm wondering if this might be the problem ? This only occurs on the connections which fail, the connections that work, the destination responds quickly to the initial SYN, and the 3way handshake completes.
Syslogs :
