Linksys Cable / DSL :: WAG54G2 Switches To Bridged Mode Every Few Hours?

Jun 28, 2012

I have a WAG54G2 working fine for more than 2 years now. It has the initial firmware version 1.00.10
 
Recently I mode it from my home to my store, where I have a already working CCTV setup. Initially the router did not work, but once the service provider removed the mac-id binding (with my previous ADSL2+ router) the WAG54G2 was connecting on DSL. However it never got a DNS value. Currently I am using it with a fixed DNS.
 
After a few days of working I noticed that my remote viewing for the CCTV was not working. On checking the router settings I saw that the router had defaulted to no settings at all. Changing it back to PPPoE did not work since the page would not render completely. Resetting to Factory settings also did not work. However simply switching off the router and restarting it worked. I let it go then. The same thing happened again within a day or two. Each time restarted the router seemed to solve the problem, however temporarily. 
 
I have the SPI firewall enabled also I have application port forwarding set for HTML port 80 forwarding to say port 1234.

Router Reboots By Itself?

Jan 8, 2011

I bought it without a a windows installation because i already had a copy of vista 64 cd which I installed when I got the computer. Then I realized vista couldnt handle the amount of ram my computer had or support some of the other new hardware, so i went online and purchased a copy on Windows 7 for 600dollars and digitally downloaded it from a non microsoft site, as it turned out after I installed it the cd validation key was not included in the purchase sadly so I was running it as trial version for 30 days.Anyhow, at some point (and it has been going on for awhile) my router reboots quite frequently when I am online playing games such as Civilization 5 , world of warcraft and CoD on this computer. Sometimes it can reboot up to 3-4 times an hour if I'm really unlucky! When I'm not playing games and just surfing the web it is rare the router restarts, and while I sleep I keep my computer online and it dont reboot at all.

So it is basically when I play online games this occurs the most. However! If I play games online on my laptop or playstation 3 the router -never- reboots, so it's obvious the problem is not the router itself since it works with my ps3 and laptop but not my stationary gaming computer

Cisco VPN :: 881 Fails After 24 Hours / IKE Key Lifetime

May 28, 2013

We've got a central office (actually quite small) where several IPSec connections connect to. Two of these connections are Cisco 881 routers. One of them works fine, the other craps out after 24 hours (coincidentally also the IKE key lifetime). When I mean "craps out", it means the VPN worked fine from the get go, until 24 hours later. Only a reload will bring back the VPN tunnel. I've verified my PFS and DPD configurations are solid, because these kind of symptoms would most likely occur when these configurations aren't in order.
 
The two 881 configurations are quite similar. The only differences between the two are some details in the PPPoE configurations and (quite obviously) the IP address space for the two sites. Both operate on the premise of a point to point connection (no multipoint stuff going on here).

D-Link DIR-825 :: Rev A Serious Performance Reboots

Feb 17, 2012

I continue to have significant performance and random reboots with DIR-825 router (hardware: Rev A1; Firmware: 1.13NA).  My ISP has checked the lines to my cable modem.  If I connect any of my laptops or PCs directly to the cable modem and work off the direct connect, all works fine with no problems for many days and even mutliple weeks.  So, the router seems to be the bottleneck/issue.

I've tried multiple settings changes as listed in the forum here.  My setup is fairly simple and detailed below.

Setup -> Internet:
-- Dynamic IP (DHCP)
-- I have disabled "Enable Advanced DNS Service"
-- "Use Unicasting" is enabled
-- I have primary and secondary DNS servers set

Cisco Routers :: WRV210 Router Just Reboots

Jun 13, 2011

I've began having problems with the WRV210 where the router just reboots.  Sometimes it may go for an hour or more then it slips into a series of reboots.  The up time varies so I see no pattern.  Contacted support they thought the device may have been defective so we did a RMA.  Well guess what?  The replacement arrived on Friday we put it in place and the same thing is happening.  We are not using any of the VPN or VL options.  Just simple PAT to a few internal machines for RDP access and an internal exchange server.  The Qos is all disabled.  It has the newest firmware which I have reflashed.  I'm at a loss to explain the behavior but it doesn't appear to be isolated to a defective device.

It's been working fine and I've been having no problems except for one.After a few hours of hosting my server, my internet connection will immediately drop down to 1.0mbps, and I lose all connection to everything until I reboot my computer.I'm using a wireless internet adapter right now and having this problem, but when I used a wired connection a similar thing would happen where my entire connection would "lock up" in a way. I couldn't connect to anything until I rebooted my computer

Cisco VPN :: PIX 515e VPN To ASA Failing After Several Hours Following Upgrade?

Feb 13, 2011

I've got a PIX 515e firewall on a branch site running version 7.2.4.7(LD) connecting via a VPN to an ASA at the HQ with 7.2.5 code running. After several hours it is no longer possible to ping either the PIX or hosts behind it on the branch LAN though the tunnel still shows as being up.  In order to bring the link back up the local PIX has to be rebooted.The connection used to work with no problems when I was running PIX version 7.2.1 software but this had to be upgraded to 7.2.4 to support the new TCP normalization commands. VPN connections to other branch sites running PIX 7.2.1 remain active with no problems. The reason for the upgrade is to implement WAN acceleration between the sites however I still encounter this problem even when the WAN acceleration hosts are not installed.In addition to the software upgrade I added the following configuration to both the ASA and the PIX: 
 
tcp-map wanx_tcpmap
 synack-data allow
 invalid-ack allow
 seq-past-window allow
tcp-options range 28 28 allow

[code]....
 
The ASA originally had this code but the PIX did not and the VPN was stable, after upgrading the PIX and adding the code the link was no longer stable.

Cisco Firewall :: ASA 5505 Locks Up After 24 To 48 Hours?

We recently changed ISPs from Verizon T1 to Comcast fiber.
 
The only change made in the firewall was the outside IP address, gateway and mask.   No changes on the internal network or the interface.
 
After a power cycle everything is good from anywhere from 24-48 hours, then all traffic locks up.  The interrface shows as being up but no traffic can get through until another power cycle.

Cisco VPN :: 1802 Tunnel Goes Down For Several Hours / Then Goes Up Again Without Reason

But from time to time, the tunnel goes down for several hours (or several minutes) then goes up again without reason.I've checked the IPSec configuration, it seems correct. Anyone has experience on the BT 2wire Gateway Router ?

Cisco Wireless :: WAP4410N Dies Every 24 Hours

Sep 26, 2012

I have two WAP4410N wireless access points powered using Power-Over-Ethernet. Both are running the latest available firmware version (2.0.5.3)They are both connected to the same LAN and broadcasting the same SSID with a WPA2 password.
 
One is using channel 1, while the other is using channel 11.There is coverage overlap where the signal from both access points hover around -75db to -85db while standing in the same physical location.DHCP is disabled, and is being provided by another network device.
 
Every day or so, devices can connect and authenticate to the access points, but are not granted an IP address (and subsequently are unable access to the LAN or Internet). For devices that had already retrieved an IP address prior to the issue exhibiting itself, the devices simply stop communicating with LAN and Internet.
 
However, I can still access each access point's web admin interface from the LAN.
 
If I reboot both devices, the problem vanishes and devices are once again able to get an IP address and connect to the LAN and Internet.Are these symptoms of signal interference between the two WAPs or is this a completely different issue?
