My internet connect works fine for hours at a time, then suddenly will get 7 or 8 General Failures while pinging (long enough to boot me off the net) then will be back to working fine immediately afterwards.Pinging 127.0.0.1 works fine. I've checked the firewall (Norton) and it has the default settings

I can access the internet just fine, but when I try to connect using a VPN It times out.When I ping the desktop in question, I get a timeout, and when I ping anything from the desktop I get "general failure".I've tried allowing echo responses through the firewall, and disabling the firewall, to no avail.
I seem to get worse range on the DIR-655 than I did on the DIR-615. I was able to walk out to the parking lot with 1 bar of signal on my phone with the DIR-615. I can get about half way there before I have no signal now that I've got the DIR-655. Are there some settings to disable that might be playing a role in this? I've got the router configured for wireless N only, could that have something to do with it?
I'm having a problem with my router a Dlink DIR-655. I know its the router because if I direct connect from my cable modem the problem does not exist. What happens is I start downloading/streaming something it will start and then just stop prematurely causing me to restart it to get it too finish. For example on youtube, I start loading a video it loads normally for 2 mins of video and then will stop. I can get it to restart if I swap video quality and then it just does same thing. Loads around 2 mins of video then stops loading.
I have tried switching browsers, and I changed my MTU size from 1500 to 1300.My motherboard is a GA-P67A-UD4-B3 if that matters. I have the latest firmware on my router.
I am using the 26 character WEP code. Was wondering if it's possible to setup a short password or PIN number. Been troubleshooting problems with a wireless blue ray player that has required multiple resets. Entering the wep code with the remote is hard!
We have been using a SRP521W as the main Router for an office with about 25 users.
So on the cable network it's about 25 computers, 25 IP Phones, 3 printers. Wireless network hold some smartphones and tablets. Computer traffic is 100% Remote Desktop.
That said, for the last few days network connectivity sucks. I think the problem is, precisely, the SRP521W. Some mornings the WAN link is down and can only be brought up by a router reboot.
There's an IPSec tunnel to HQ.
Wireless network was moved recently to a WAP121 to offload the SRP521W. It has two networks: internal and customers with two VLANs.
CPU Usage is around 30-45% all day and spikes to 100% sometimes. RAM Usage is 40-45%. I do not know if this is "too much", "average" or "really low load".
Anyway, time for questions: a) How can I get a table of active connections on the firewall/NAT to see if there anything "strange" on the network traffic that maybe causing issues?
b) Is there any know bug in the VLAN handling of the SRP that maybe causing the issue? (it's one of the latests changes introduced).
c) If the problem is that there's too much load for such a small router, what replacement would you recommend given the details above? (remember I do not really need wireless on the router as I have the wap121).
I have a situation, where I dont need email and where is no SMTP server in this network, but I need CCO-access for EoX/PSIRT from LMS. Because both settings are in the same menu and LMS4.0.1 does real TCP:25 checking for given SMTP-server before can apply, I cant save my CCO-credentials. What can I do?
My netbook keeps getting DNS Lookup Failure messages. This happens about every 20 minutes, give or take, though sometimes it can go longer before the failure. I can "solve" the problem by quickly repairing the network connection, but that's tedious. It happens only on my laptop and not on my housemate's desktop (wired connection) though he did say that it happens to him on his laptop as well. In looking around I thought the problem might be because i'm using Chrome, but it happens on Firefox and Opera as well.
So, I just upgraded my mobo/cpu (Z77A-G45 and i5-2500k) and I'm having an issue with my connection as it seems to drop every 5 to 15 minutes constantly and have no idea what exactly is wrongThe kicker is my old mobo did the same thing and I had to do something in win7 to fix it (not sure if it was the drivers or what) but I just can't remember what exactly.
Just got a WAG120N modem/router , everything is set up and works fine.But I am very disappointed with its wifi range.After using an iPhone and a PSP , I found that, its range is 1,80 meters only, in empty room.Is it faulty ? I cant believe its range is too short although I know that its not "enhanced speed & range" as typed on box.I tried all combination of channels/protocols with no success and it's already flashed on latest version. I really cant connect to my wifi devices.
I bought an E4200 to replace an old buffalio Nfinity. The range on the 2.4 and 5 GHz have both been extremely short -- shorter than the old Buffalo. 1 meter from the router, I get five bars on the laptop and 3 bars on ipad. 3 meters away with direct line of sight, the laptop dips to 4 bars. Down the hallway about 4-5 meters away, the 2.4GHz is one 1 bar on laptop and ipad. the 5GHz is gone. This is two rooms away from the router in my apartment. Isn't that a bit shocking in terms of performance? A webcam that is two rooms away registers a 6% signal from the E4200.Does this sound like faulty hardware, e.g. bad antennae? I would think it is something about the build of my apartment building, but my old buffalo did MUCH better than the E4200. two Ipad bars where the E4200 has one...and in very unstable condition.
I have a Cisco WISM2 installed on Cisco cat 6509, with 39 indoor (3502i) and 14 outdoor (1310G) Access point, so the problem i am facing is that, the controller recognizes all AP and they are all configured and working well, then the signal of the outdoors (1300) its broadcast in a very short length like 60 meters, and i don't understand this is likely having a problem with a controller software version or ... being at 3m, my card does not show excellent signal strength and yet with the indoor thing are Ok.
I need to implement VSS on 6500 equipped with Sup720-10GE and WS-X6704; considering that this last 10G card doesn't support VSL, I need to realize VSS interchassis connections on Supervisor 10G interfaces, but I only have X2-10G-LR. Considering that the 2 6500 are in short distance (few meters): is it possible to use 10G long range optics and, if yes, do I need some additional patch?
I am an accomplished developer in Microsoft technologies, however networking has always been my weak point. I have always managed to be in jobs where my lack of knowledge in networks has not affected me, so I have never bothered to learn anything.Are there any good books out that would teach me the basics of things like tcp/dhcp/vpn/dial up networks/routers and other netwokring terms.
I am have 3 machines int he house connected to the internet but one does not have internet access. It shows connected to the wireless network and from the command prompt there is an ip assigned to the laptop. But i cannot ping the gateway or any ip I get General Failure.
We are a new call center company and want to configure the network to setup the predictive dialer, work properly.how a network could be setup to configure predictive dialer.
I think there is a problem with the settings on my router or something like that. When I watch videos on streaming sites the load bar tends to go up but only so far before freezing. If you slide the button along once the umbrella spinny thing gets going then the load bar will kick back into life again for a few seconds before freezing! The problem also effects downloads. Anything that takes longer the 5 or 10 seconds will fail. This has stopped me downloading simple things such as iplayer and flash updates. I know its not a problem with my computer as it effects all the machines that pass through the house. Were currently getting Virgin wireless broadband (so I dont think its a speed issue).A tecky friend of mine thinks it might be something to do with the 'packets' of information or the channel that my router is operating on
There is a problem with establishing an internet connection between my laptop and any wireless network, and hence the internet cannot be accessed. Though, the connection can be established locally between my laptop and the wireless network for a short while before the connection is lost locally. There is certainly no problem with my current wireless router as there are internet connections between the wireless network and other devices. Prior to using the current wireless router, I used Linksys WRT54G for internet connection until recently when there was no connection between all devices and the Linksys wireless router, so I changed my wireless router to the current one. However, the problem still persists for my laptop. I can only get access to internet when my laptop is connected to the router using ethernet cable, as well as when my laptop is connected to the main cable modem using the same cable.My laptop model is Fujitsu Lifebook S Series and my laptop is running on Windows Vista Service Pack 2 and my current wireless router is Belkin N300 Wireless N Router Model F9K1002v1.What I have done so far are that I have ensured that the DNS client and DHCP client service are enabled and that I have used the method of "/release, /dnsflush and /renew" on the command prompt.Below is the /ipconfig /all description when this laptop is connected to the cable modem using ethernet cable:

Even before I did the latest firmware flash I couldn't select short GI under Advanced Wireless - it was simply greyed out even though WMM was enabled above it. Now after a factory reset and recreating all my settings I still can't select it.
I have a new Alienware X51 running Win 7. It's connected to a home LAN, both wired and wirelessly. For the prior two days internet connectivity has been fine. Today, the PC will not connect to the internet. The Network and Sharing center in control panel shows that the PC is connected to both the wireless network and the wired network, but with no internet connectivity. All other computers and devices in the house are able to connect to the internet. Tried restarts, virus scans, router power off/on, ipconfig /release and renew, all with no luck. When I try and ping other computers in the LAN or the router I get a "General Failure" message.
how to hide Wireless SSID via Wireless controllers (one I am using is 5505)
Currently anyone can attmept to login to it as i cant find any options to hide it! Screen shot below)
what measures I should take to secure the APS and from access, currently considering port security and static mac addresses on ports; traffic is already got ACLS on its vlan. I have little to no experience on Wireless devices.
I made a custom-built V1 Windows Home Server that I really would like to be able to remote access. I have tried the Netgear 3700, but it did not allow remote access. A D-Link DIR-825 does, but it, and many D-Link products, have a persistent problem of requiring a reset due to dropped connections. I have had 2 of the DIR-825's drop connections. I have been told that their QoS components cannot handle the load on them and fail, causing the drops, but I cannot corroborate that.Perhaps what I need is a router that allows "NAT loopback"? This way I can see the WHS Console verify that I can access the server from outside my network. I have tried to do so with the above routers via a 3G connection on my iPhone 4 and all except the D-Link failed to allow access to my WHS.
I should add that I am using a D-Link DSL-520B modem on ATT DSL. It is a 6MB connection from the ISP. Previously the modem was in "bridge mode" on the D-Link router. Also, contacting ATT I was told they do not block any ports. I have tried forwarding the proper ports (80, 443, 4125) for the WHS, but that has not given me remote access. I did get them by enabling UPnP on the D-Link. Is all this an issue of needing the modem on "bridge mode" in order to work properly? Any router for my needs that allows remote access (NAT loopback needed?) and also has a solid connection? Gigabit ethernet is a must have too. Otherwise I am open to options. I would like a combined router/modem unit to make things a little easier.
I have over 20 units doing the same thing and it seems to be a software isssue but i dont see any bugs or posts on it. This is only on 2960S switches and not 2960 or 2960G units.
If i use the password reset feature to break the units into rom and then type "boot" instead of power cycling the unit, they will fail MBIST post tests. If the unit is power cycled or left to boot normally on its own, there is no issues and all post tests pass. I know MBIST is Memory Built In Self Test and was thinking maybe breaking the unit into rom disrupts those memory tests for some reason. I tried the following software and got the same results with all of the images:
122-55.SE2 122-55.SE 122-53.SE2 122-53.SE1
Logs attached are from the same switch, one with password reset procedure used and while left to boot on its own.
Me and my friend is currently setting up a Xen test environment. As you can se from the picture below we are running a Cisco ASA 5505 to reach the network from the outside.But the problem is that we want to reach the virtual pfSense's subnet's through the Cisco AnyConnect VPN. And currently the pfSense's are only configured with a public ip and a virtual interface to the VM's.could solve this problem by buying another PCI NIC, so that we have a physical link from the "pfSense box" to a tagged VLAN on the switch.But we are having problems configuring the switch to general vlan's. Cause Xen can't have it's management interface on a tagged VLAN directly from the XenServer,but the switch can tag the packet when it reaches the switchport. I would like to have "switch port general allowed vlan 2" for admin and 10 for "LAN"And then trunk the port to the Cisco ASA. But again, Xen stops me from doing this.
under ASA Version 8.0:Are NAT's processed from top to bottom or general to specific?I have a many-to-many NAT that is taking precedence over a one-to one-NAT. In what order are they processed?
For years I have received occasional complaints about users being dropped from WiF and then reconnecting like a minute or two later. I wondered what tools people on the Forum used to troubleshoot this transient problem. Cisco APs like the 1200 don't seem to inform about why someone left. One thing that has been very useful over time is using Network Sumbler to see what WAPs are in a vicinity and make sure there is not channel overlap. How to troubleshoot transient wireless network drops?
