My wifi connection seems to 'brown out' but not consistently. I just had comcast tech out yesterday and he said things seem good up to the cable modem.I just replaced my cisco e3000 with new cisco 4200. No problems when plugged into lan but my gut is telling me it still is in the "feed" and not the router. Anyway to track the latency of the broadband? See if if it comes and goes intermittently?

my laptop (asus) has been having issues with my WiFi. On startup, the laptop will (usually) connect to the internet fine, but after a few minutes, usually without any specific cause, it will disconnect from the internet, and the toolbar indicator will go from full signal (full bars) to no bars and a yellow triangle, saying limited access. When I try to reconnect, it will say "connecting" for a few seconds and then will say "cannot connect". I have to leave it for a few minutes every time before it will randomly reconnect until the next incident... My other two pc's (one Windows 7 and one Windows xp) do not have this issue, but sometimes other wireless devices in the house (iphone, ipad) will have a problem where the WiFi indicator will show full bars but I will not have internet access. I have to disconnect and reconnect in order for it to work. Again, it happens sporadically with no obvious cause...

I've been having a problem with my wifi connection.I give my neighbor $15 a month to use his connection, so I have no control over the router.I'll be surfing along or just checking mail or whatever and out of the blue my connection stops. A little yellow triangle "warning" sign covers the signal strength meter in the lower right corner. If I click on the signal meter, up pops the list of wireless connections available to me and says that I'm connected, (but I'm not). So I go to the network and sharing center and sometimes this alone will restart the signal but usually I have to run the troubleshooter and the signal will come back with no explanation of what the problem is.While in the network and sharing center, my connection to the router looks clear and connected but shows a red X over the connection between the router and Internet.

This does not happen when I am connected directly to the router with a Ethernet cable. I have redone all the settings many times(like 6) and Im still having the same problem.
I really dont want to have to buy a new router
I have an ancient Compaq V2410 notebook which has started to drop my home Wifi connection recently (started about a week ago). At first, I thought it was the install of Firefox 8 as it froze and crashed but it happens with Chrome, IE and even when not running a browser.
My ISP is O2 in the UK and I have a DSL2+ service with the O2 Wireless Box II. I have gone through a power down cycle on the router and it continues to work with my ethernet-connected desktop PC. I have changed the Wireless Card in the notebook but fault is still intermittent. The notebook was also set to OpenDNS servers but that has been set back to Automatic DNS servers.
The notebook has the latest free versions of Avast Anti-virus & Comodo Firewall and the main issue is that the notebook has 640Mb system RAM which means that various Windows services have been Disabled or set to Manual.
I can sometimes recover the Wifi signal by switching the wireless on/off but it is sporadic. I have attached the Xirrus WiFi screenshots at startup, at fault state and at recovery state together with the ipconfig.txt output.
E4200 Version 2.0.37.131047 disconnects my wireless clients intermittently. I am seeing it mostly on the 5Ghz band but that is where most of my clients are connected. I have all the setting in advanced tweaked per cisco best practice. It just seems to reset every so often. Wired connection is not disconnected.

In the lab i managed to enable LACP between Cisco 2960 and juniper EX-4200 and works with the atached configs that i found on juniper forum. Also LACP between Cisco 2960 and WLC works with te same config, but never between the WLC and Juniper. I've tried with passive mode and slow mode, always seems that juniper is not seeing the WLC BPDUs. I tried with WLC 4402 and 5508 both with 7.0 firmware.
I would like to explain my situation. My house has 2 floors. My broadband modem is on the 2nd floor. I have an ea 2700 linksys router there, connected to the broadband modem. However, i can't get a good wireless signal on 1st floor, therefore i bought a second router, an e 4200 linksys.
I searched the web, and connected both routers via Ethernet cable, plugging them in lan ports. The ea2700 was only configured wireless security passwords. The e4200 had it's ip renamed to 192.168.1.2 and DHCP server turned off. Well, i have a problem here. the second router, doesn't give me access to internet.
I had windstreams modem "speedstream 4200" but parents for whatever reason thought the 4300 would change everything. With the 4200 I was open for gaming, could connect. With this 4300 I can't connect to anyone at all. I disabled DHCP server in my rotuer and that aving more fails than succeeds. (in connecting to people).My router doesn't have bridge mode but my modem does, I don't know what it does in the modem. My friend had the exact same problem I did and he put his router in bridge mode which I do not.

My linksys 4200 was set up some time ago for me, (unsecured) and was working fine. I was having problems with just 1 desktop that was using a usb wireless adapter, so I went and purchased a new cisco ae2500. While connecting I used the push button that it described, only it knocked out the network, and all the other computers are now off of the network. The new network(s) are Cisco_WPS_42526 (secure) and Cisco_WPS_42526-guest. Not knowing the network key and the guys that set it up are gone, I tried the guest. WHICH REQUIRES A PASSWORD!!!! I can now not get ANY of my computers online! How do I find the security, or the password? Why would you need a password for an insecure network anyway?

View 3 Replies View Related[code] Whenever I am browsing online, every once in a while the internet just cuts out. It still says I am connected to my wifi network, but there is "limited or no connectivity." Whenever it happens, everything on the network loses its internet at the same time. In the household, there is one PC (mine), one Mac (my wife's), one iPod touch, and 2 iPhones that all connect to the wifi. The vast majority of the time, when this problem occurs, simply unplugging the router and then plugging it back in fixes the issue.Sometimes however things are different. Especially lately, I sometimes get an "IP conflict" error message. It says another device on the network is using the same IP address. Sometimes with this error simply unplugging and replugging in the router works. Sometimes the router has to be reset twice before things start working again with this error. The error doesn't happen every time the disconnect occurs, but it seems to be getting more frequent lately.Sometimes the disconnect happens when I am playing an online game that requires a constant connection to the internet. Sometimes this goes as usual, where a single router reset fixes the problem. However, sometimes this situation gets more complicated. One game in particular (League of Legends, if it matters) has this problem all of the time. When the internet disconnects while this game is playing, I do not get the "limited or no internet" warning. Instead, the computer seems to think that it is connected, and that the internet is working.
During this scenario, resetting the router once is never enough. After resetting once, the wifi reconnects and now it realizes something is wrong. After the first reset, the computer seems to "realize" something is wrong after all, and I am connected to the network but this time with the "limited or no internet" warning. A second router reset after this usually fixes the problem.Last night the worst disconnect happened yet. It was in the middle of a game, and the internet cut out, with no warning on the network. After one router reset, the wifi network reconnected immediately with an "IP address conflict" error, and then I was connected with "limited or no internet" on the network. I did the second router reset as usually required, but nothing happened. After a second and a third reset, there was still a permanent "limited or no internet" warning.I tried hardlining in directly to the modem and there was still no internet. Running the network diagnostic on my laptop fixed it however and I was connected to the internet. However, wifi still would not work, even after trying the diagnostic again. Running the diagnostic came up with an error that the DNS server was not responding and so nothing could be done.This time I reset everything. Unplugged both the router and the modem and left them unplugged for 30 minutes. When I turned everything else on again, same issue. Connected to the wifi network, but "limited or no internet." I unplugged everything again, left them overnight, and this morning after plugging everything back in the internet was back.A few final points I think might be relevant:
1) When checking the system event logs, it's usually a DNS error that I get (see event logs, 1st attachment).
2) This disconnect error seems to be more prevalent when more devices are on the network. As I said, they have gotten more frequent lately, especially the IP conflict warnings, since the 2 iPhones were added a few weeks ago. 5 months ago when it was only my PC on the network, these issues were practically non-existent.
3) It's a Belkin wireless g-plus router. Model # F5D7231-4 version 1213. It is an older router.
4) This has been happening for almost a year, but just recently gotten so bad I have to get this fixed, especially after last nights that could not be reset no matter what.
5) I'm not sure the disconnects have ever happened why the PC is not connected. That may not be relevant however, because my PC is almost always on since I work from home, while the iPhones, iPod touch, and my wife's Mac are only connected periodically.
6) This error has occurred while my PC is the only device connected to the wifi network, but it seems much less frequent.
7) The time the error seems most likely to occur is when another device connects to the network, such as when my wife first gets home from work. This is not exclusive however, and the DC's can happen at any time.
I've seen that people want ping tests and ipconfig /all tests so I will post mine. I will edit my post with the same tests done the next time this dc happens. I've also included a screenshot of that xirrus wifi program. [code]

View 8 Replies View RelatedWe have a Cisco ASA and recently purchased a cisco small business srp527 router. It is connected to our ADSL2 connection and is working fine. I have configured the device with an ipsec tunnel using an ike profile and the tunnel is created successfully with packets traversing the tunnel. However packets are being dropped intermittently, with no cause. The link is currently not being utilised, there is no load on the network however when I ping Google and any address subject to the rules of the tunnel i notice that a single packet is dropped every now and then.
View 0 Replies View RelatedI installed the RV220W Router in my office about 2 weeks ago and everything works perfectly for 3-4 days but then my connection drops out and the router must be restarted to restore connectivity. When I say the connection drops basically the internet connection drops out and my network connections drop shortly thereafter. Usually the wireless connections lose connectivity followed within a few minutes by the wired connections.
Â
Is there something in my firewall settings that could cause this issue? I have checked with my ISP to verify there are no problems on their end.
We just upgraded from 8.2.4 to 8.2.5.20 on each firewall. The Primary and Secondary work when they are standalone but, when we connect the fail over link from the Primary to the Secondary, invariably, one of them will go into a constant boot cycle and one will be active but, external users will be intermittently dropped. As soon as we unplug the fail over, the firewall that stays up behaves normally. This is with 8.2.5.20 code or any other code for that matter?
View 2 Replies View RelatedVPN tunnel between ASA 5520 ver 8.0(4) and a remote Juniper firewall keep tearing down during Phase 1 rekeying. After the rekeying process fails, manually pinging one of the remote hosts that are proteced behind the Juniper firewall,initates the tunnel renegoation and rebuilds the tunnel successfully.
Â
When the tunnel is down, sh crypto isakmp sa shows no active SA for the remote peer. That indicates the PHASE 1 negotation had indeed failed.When the tunnel is working, sh crypto isakmp sa indicates an IKE role of Responder - always.Clearly that also means Phase 1 negotation works only one way, i.e. negotation initated by the remote Juniper unit only.
 Â
Interestingly, the Syslog server logged the following SNMP trap messages at the time rekeying Phase1.Note, Line#2 and #7 and wrapped to the next line for easy of reading.

Line#1:Â Â IP = Remote-Peer-IP-#, Starting phase 1 rekey
Line#2:Â Â IP = Remote-Peer-IP-#, IKE Initiator: Rekeying Phase 1, Intf outside,

Line#3:Â Â IP = Remote-Peer-IP-#, constructing ISAKMP SA payload

Â
As I understand from the above syslog trap, the Responder ( the ASA unit this time) started Phase 1 rekey (Line #1). It prepare a message to be sent to IKE Initiator, that it is about to start rekeying Phase 1 (Line #2). Down on the next line, it indicated that the local Proxy, remote Proxy and Crypto map as N/A ( not avaiable).Why would the ASA unit send N/A message as shown in Line#2, is that normal?

I've been looking on the forum and trying to understand some of the solutions and checklists already posted, but they don't make a whole load of sense to me unfortunately.
The firmware on the router is 2.27. The only change I have made to the system is that my wife's lan card seems to have died a death last week, and her computer is now connected by wireless. My computer is now the only one connected to the router by a lan cable.
There is something I don't understand. Under setup / network there is a dhcp reservations section. Pretty much every device seems to have a reserved IP address, and some of the devices that are reserved we no longer own. My son does gaming and wants a constant IP address, and my computer might need a permanent IP (don't know - just guessing here). Should all the other computers be allowed to sort themselves an IP every time they log on? Most of the devices have expires never, and some of the devices have the blue link that I can click for revoke and reserve with a time by them.
Am I barking up the wrong tree here and this lot has nothing to do with the dropping connection? What do the revoke / reserve and times mean? What happens when the lease runs out? Will the connection drop on that computer and it will have to try and connect itself again, or does it start a new lease every time it logs on to the router?
We're running Cisco Secure ACS V5.1 on a Linux platform to manage remote access to many networking devices. This has not been in place long, and is generally working OK. However, whenever I set the parameters of the user authentication to 'disable user account after X days if password was not changed', so as to comply with our internal security regulations, the user IDs seem to disable themselves intermittently, irrespective of whatever number of days I put in this - this can be a couple of days after re-enabling, or just a few minutes.
Â
This can be found in the advanced tab here: System Administration > Users > Authentication Settings.In the mean time, we are having to set the user authentication to be non-expiry. Is this a known fault with this version of software? If so, would there be a patch available, and how would I go about obtaining it?
