D-link Dir-655 :: Wifi Connections Dropped Periodically
Mar 5, 2011My DIR-655 drops WiFi connections every few days. All wired connections are fine. Rebooting the router fixes the problem at that time. Cable modem works perfectly fine. [code]
I'm sure I'm missing some devices, but that should give you the general mix of wired/wireless devices that I use. I'm single with visits from my son every other weekend, so network traffic is not that high at my house. I've had this router for a couple years now and didn't use to have this problem. I've been updating the firmware, and I suspect this problem happened after on one those updates. I just don't know which one. Also, I didn't use to have any neighbors with Wireless Routers (that I could detect), but recently there have been 2 who have gotten them. I was hoping this was a problem that D-Link was aware of, but that does not seem to be the case. I would hate to have to go out and buy a new router (not D-Link).
Cisco Firewall :: ASA 5510 / Dropped Packets In VPN AnyConnect Connections?
Dec 5, 2012Our Cisco ASA 5510 running 8.4(4)1 just started dropping packets and our AnyConnect clients are seeing horrible performance. The system is extremely slow compared to just a couple days ago.Nothing has changed on the system. I can post the configs if needed.

Cisco VPN :: ASA 5510 - Client Connections Getting Dropped
Mar 30, 2011I have some remote locations that connect to my ASA 5510 cluster (Aktive/Passive) using the Cisco VPN Client, from which the connection gets disconnected at random intervals (could be 5 minutes, but sometimes after 15 minutes). However, some other remote locations do not have this problem. All locations have the same VPN client configuration (distrubited by pcf file).
I already disabled isakmp keepalive on the ASA but this did not work. If I read it correctly, the Cisco vpn client logging shows that the ASA initiates the ending of the connection.

Cisco Firewall :: ASA 5520 - VPN Traffic Is Getting Dropped Through Firewall
Apr 8, 2011Our Local Network is behind the CISCO ASA Firewall.Whenever we are accessing to Client VPN server,it is getting connected but after few Minutes (May be 5/10/30 Min),the sessions are terminating. The same traffic through PIX is no issue , only with ASA Firewall. See the following Error and request you give the possible root cause for this.

Cisco Firewall :: 2921 Firewall Allow Rules Being Dropped
Jul 5, 2012 I am configuring a 2921 with enhanced security using the CCP. I have found a behavior that seems strange to me and I'm not sure if I'm misunderstanding something or missing a setting. It seems that if I create a firewall rule to "allow" traffic through, that traffic gets dropped, but if I set the action to "Inspect", the traffic comes through fine. I can actually reproduce this at will by setting up a rule from out-zone to self to allow traffic and I cannot telnet into it from an external ip, but if I change that rule to "inspect" i can connect fine (i dont want that rule set up permanently, was just using it to test the firewall).
If I set the allow rule to log, I see the following line in the application security log:
(target:class)-(ccp-zp-out-self:user-fw-ccp) Passing telnet pkt 1.1.1.1:58141 => 2.2.2.2:23 with ip ident 0
(where 1.1.1.1 is the external laptop and 2.2.2.2 is my WAN IP address of the 2921)
So it looks to be passing the traffic, but that traffic is getting dropped somewhere because the connection is unsuccessful.
Is this the expected behavior of "Allow" action? Is there something I can do to make sure "allow" traffic actually gets through?
Cisco Firewall :: 6509 - FWSM With Packets Dropped
Jun 9, 2013I happen to noticed the FWSM was dropping packets at about 387 packets every 5 minutes. My outside FWSM is WAN facing and has a 1gig link (35% utilized) my inside facing has about 100 downstream switches to the closets. I do not see my 6509's back plane is being over utilized and my understanding of the FWSM show be go for 5 gig so it isn't oversubscribe. Why i am seeing packets dropped?

Cisco Firewall :: 8.2.4 External Users Will Be Intermittently Dropped
Jan 14, 2012We 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?

Sep 5, 2012We are implementing a new corporate headquarters and have bought a Cisco 5508. I have two connections plugged into the 5508 in ports 1 and port 2. Port 1 is for all internally wireless networks and connects to our core 6500 and use an external DHCP server scopes. Port 2 is for our guest WLAN and connects directly to a public network switch in front of (outside) the firewall. For the guest network, I have setup a vlan on the controller for dhcp and the interface setup to that vlan and dhcp scope built on the controller. how or can I NAT the internally addressing for the guest network to the public IP address on the controller. Essentially I want to drop of guest network traffic outside the firewall and not have to deal with setting up the firewall for any aspect of guest network traffic.

May 30, 2013We are working with an ASA 5520 and it seems there is an issue with some email messages sent throught it. When there are many recipients in the emails the email messages are not sent, and I have revised the server an the only thing I see is connecting dropped. When I went to see ASA log and see this log report: ESMTP Classification: Dropped connection for ESMTP Request from 'interface': servername/portnumber to outside: IP address/25; matched Class 2: cmd RCPT count gt 100 tcp flow from interface:servername/portnumber to outside: IP address/25 terminated by inspection engine, reason - inspector disconnected, dropped packet. So I think there should be an inspection of ESMTP packets and if they detect an email message sent to over 100 addresses, then the packet is dropped, am I right? if so, what should I do to let those email messages be sent?

Cisco Firewall :: 2911 - Immediate Gateway Dropped Ping Traffic
Jun 13, 2011I have a a firewall policy on a Cisco 2911 - the zone policy from OutZone>InZone basically drops everything apart from inspected traffic on the opposite direction and a few essential traffic generated externally (such as Outlook web access and E-mail exchanging). However, I seem to be getting a lot of firewall drops coming from the immediate gateway of the ADSL WAN address to the internal IP range on port 3. I get about 10 hits every 5 seconds.
Policy:
policy-map type inspect FWPol_Out-In
class type inspect CCP_PPTP
pass
class type inspect FCMAP_In-Email
pass
class type inspect FCMAP_In-OutlookWebAccess
inspect(code)
%FW-6-LOG_SUMMARY: 1 packet were dropped from IMMEDIATE WAN GATEWAY:0 => INTERNAL IP ADDRESS:3 (target:class)-(FWPair_Out-In:class-default), the immediate gateway would ping an internal IP address? Keepalive? Could this be stemming from another problem? The traffic wasn't generated internally as all InZone>OutZone is inspected.

Apr 10, 2012My internet disconnects every 15 minutes or so for about 10 minutes and it is getting really annoying. It started last night. I installed the HideMyAss add-on for Chrome and I think that may have something to do with it. Since then, I disabled and uninstalled the add-on, yet the issues continue. When I try to open a page with Chrome or Firefox I get these messages:This webpage is not available.The server at www.google.com can't be found, because the DNS lookup failed. DNS is the network service that translates a website's name to its Internet address. This error is most often caused by having no connection to the Internet or a misconfigured network. It can also be caused by an unresponsive DNS server or a firewall preventing Google Chrome from accessing the network.I have tried the Chrome recommendations with little success. One more thing, it is not just my computer. Everyone in my house is periodically unable to access the internet. Our service provider is Optimum and we have a Belkin Router. I changed all of the security settings on the router, yet the troubles persist. url...

Jun 14, 2011I have two Cisco ASA 5520's running software version 8.2(2) set up in a HA pair. The L2L vpn is set up and works as expected between this site and another. The issue is that every few months, one subnet of the VPN, the same one all the time, stops forwarding/receiving traffic. The device in the remote location is not a Cisco device but I am certain the issue lies with the ASA as when I fail over to the slave device the VPN works again, failing back again however stays with the subnet still not passing traffic. I need to reboot the device before it starts forwarding traffic on the subnet again.

Mar 22, 2012I can install things, run CCleaner, and do other basic tasks. I've been stumped about this issue for months and after repeated, and failed, attempts to resolve it via the ISP. I've done searches via Google, this website, and all the other places I can think of, so hopefully I didn't miss a solution to my problem. When playing games online, my internet connection will occasionally drop for 5-8 seconds, every 5-10 minutes. Sometimes, the game will allow me to reconnect after a short lag spike. Other times, I must meet a breakpoint for getting booted, and I'll have to leave the game.
View 12 Replies View RelatedNetgear WRN2000 - Internet Drops Out Periodically
Apr 5, 2011I'm currently writing this from a laptop. It can access the internet perfectly, with no dropouts and no speed issues. However, my desktop PC is a different story. When I purchased the PC, it came with a standard wireless PCI adapter which really wasn't doing the job. It couldn't pick up my router from just one story above, where my laptop could. I decided to buy a new wireless adapter that would hopefully fit the bill. Unfortunately, again it didn't pick up the router from downstairs. Trying a different tack, I purchased the Netgear WRN2000 as an access point that would increase the range of my router. I connected my PC to this after configuring and all was going well for a while, until now. Now, every 1-2 minutes, the internet will slow to a crawl for 30 seconds or so, and while comparing speeds via the laptop (connected directly to the main router) and via the PC (connected through the extender to the router), the laptop clearly has the speed advantage. This is more noticable when playing games on my PC, such as Call of Duty. Every 1 minute or so, the game becomes unplayable due to lag for around 30 seconds, and sometimes this happens constantly. I'm unable to work out if the WRN2000 has a problem, or if it's interference. I actually tried connecting my PC to my laptop via ethernet, and bridging the 2 connections, which seemed to work for a day or so, but now does not. Also, i'd be willing to purchase a new PCI wireless card if anyone has any recommendations for one that has a strong signal range.

Dec 17, 2012My laptop is having trouble connecting to the internet. Some of the time it is fine, but at other times it will not connect to my home wireless network (or any other open ones I can find) despite the network being in full signal.The only advice offered by the troubleshooter is to reset the wireless router. This does work (but is very irritating to flatmates!) but doesn't prevent the problem recurring. Only my computer has an issue, and sometimes it will manage to connect to the internet by itself, seemingly spontaneously. The laptop is set to connect automatically, and when not working it also does sometimes attempt to connect, (i.e. it says 'connecting') but cuts out again before managing it. The problem can last for a few minutes or several hours.

I have updated my drivers for my wireless card to the latest, flushed the ip on my desktop that the modem is connect to a dozen times. The only way to sometimes fix it is to manually log in to my router and release/renew the ip address from there. Sometimes it will work, sometimes it won't. When it does work, it will work for about a week and then stop working for no reason at random times.The errors I keep getting are:Identifying network (which runs infinitely before cycling back to no internet connection)Connected with no internet access.

Mar 26, 2012my E1000 router locks up and I lose Internet connectivity until I unplug the router's power cord, wait for 10 seconds or so, then plug it back in and let it restart. This seems to be triggered (a.) when I land on a web page with intensive graphics, etc., that takes a while to load, or (b.) if I launch a web page really quickly while another one already is up. it doesn't just happen spontaneously when I'm working on the computer. This computer I'm working on is old and slow, which is why as per my earlier inquiry about having to reconfigure the router and network , I'm looking at changing to an up to date and faster model. I just updated to the latest firmware, probably a week or so ago, but the router was doing this before then and still is doing it now.

May 4, 2013Rev B, recently updated firmware to 2.10NA hoping to resolve the problem.WIFI is disabled.DHCP is disabled (I run a SBS 2008 server, but for testing i static ally assigned IP info on my test PC and disconnected all other systems including the server).Before updating the firmware, the router would hang for a couple minutes and then be OK for some random period, usually more than a few hours. After updating and resetting to factory defaults, I'm now lucky to get ten minutes of service before it hangs. The "globe" light goes out, blinks yellow and then within 20 seconds or so, goes out for good. At that point I can't even connect to the router's admin login page. I either have to power cycle the router OR the cable modem. I have confirmed it's the 655 by reconnecting my old (and I guess more trusty Linksys WRT54G. Same settings, same WAN MAC and WAN IP, no problems after many hours.

Cisco Firewall :: ASA 5510 / Multiple VLANs Behind Single Firewall Segment?
Feb 5, 2012I need to create a firewalled segment that not only separates hosts from general population, but also from each other. The solitary confinement of firewalled segments.I know that I could create a bunch of sub-interfaces, one for each host or group that needs to be isolated, but I'd really rather not have to do that if possible. 1) It could become a management nightmare between ACLs and sub-interfaces and 2) it's a waste of IP addresses.s there any way that I can create a bunch of separate VLANs behind the firewall and have them all terminate at the firewall, using a single firewall IP address for the gateway?
VLAN 1 - hosts 1.1.1.5 and 1.1.1.6VLAN 2 - hosts 1.1.1.7
Firewall DMZ Interface - 1.1.1.1VLAN 3 - hosts 1.1.1.8 and 1.1.1.9
This way, the hosts are isolated and can't talk to each other unless they're on the same VLAN.I'm working with an ASA 5510 running 8.2.4(4).
