I've been experiencing problems with internet speeds at my church and my home. They both have security keys, but many people use it. I was wondering - Is there a free tool to monitor who/which device is taking up all of the bandwidth? Something that kind of points out, "Hey, this guy is really slowing you down". Possibly even (But not necessarily) kill their connection?
View 1 RepliesWe've recently upgraded our switches from 10/100 over to FOUR Dell 2848 (GB Managed switches) and using one as a director (fiber uplink).We are all on GB networks now and we've been running into issues tracking down what's hogging up most of our bandwidth (local area network) throughout our company.We need to track down which machines are copying data to servers and vise versa.
View 1 Replies View RelatedMobile devices are saturating our medium sized enterprise network. Examples of these devices are iPhones, iPads, Kindles, Droids, etc When a device is authenticated on our APMobile wireless network and downloads updates, email, or music our Network bandwidth is consumed. Services/Applications are no longer available, such as VoIP. Basically, this is an internal DoS.I have done some research and an example of this problem is an ARP Storm but currently clients obtain IP addresses form our DHCP server, which acts as a proxy for the clients and if effective against deliberate attempts to craft packets that create ARP Storm. In addition we configured the WLC to disable ARPunicast processing via the CLI.The following link is from Cisco's site. It is the ARPstorm that we originally thought was the cause but after more researching we found it wasn't this exact issue - http:[url]....why iPhones frequently take down our network? Could this be a configuration issue with our firewall (Cisco ASA 5520 running version 8.4(2))?

View 2 Replies View RelatedMy old Actiontec M1000 modem recently died and my HP nc6120 with windows XP can not connect to the wireless network through the new Actiontec C1000A model.It connected wirelessly through the old M1000 moden. Window icons on the screen indicate no wireless network is detected. When I view the available networks and log in to the assigned network with its password, it looks like it is trying to connect but does not. It will connect through the ethernet link-up. I don't have any other wireless devices to connect to the network. I have updated the drivers for the wireless card through HP. I have taken the HP nc6120 to the Geek Squad and the wireless card connects with their network. I seem to have a compatibility problem with the old HP with its XP windows operating software and the new modem system. I have tried to reset the ip addresses, but this has had no effect. However, I do have purchased AVG protection software operating on the system, which I am not sure how to shut off. Is this a problem with a too advanced modem for an old style HP with an XP operating system? Is there a modem that I can downgrade to if it is? [code]

The problem is that every single time I try to connect to any wireless network, I get a message that says "Connecting to the network is taking longer than usual."The network almost always connects eventually (about 2 minutes), and once connected there doesn't seem to be any other problem.This has been going on for about 2.5 months. It began shortly after I restored the laptop to factory default.
View 11 Replies View RelatedSo I have a current port-channel between two 6ks that I need to upgrade. There's too much traffic and the port buffers on the SUP7203B sort of suck. Microbursts are causing overruns like mad. Im going to move the 2x1gig port-channel to a 6724 and make it a 3x1gig port-channel. The switches carry production traffic across the link to the tune of about 400 meg during the lowest load time. Initially, I thought that I couldn't move the port channel without temporarily taking down the link but I think I have a workable solution now. Has anyone done this successfully before? Im curious what others have done. Also, to make matters worse, the existing port-channel is 'mode on' and I want to migrate to 'mode active' in the new channel

I work on a college campus that has thousands of students a day accessing our wireless network. We have broadcast SSID that the students use to connect to the internet. The students usually have more than one WiFi enable device on them and their laptops and phones both take an IP address, but they are only using the laptop to authenticate while the phone is associted, but not authenticated. In the meantime, I have several thousand IPs being used by their phones/iPods etc. Is there a way to revoke the DHCP lease if the client does not authenticate within a specified time frame (i.e. 10 minutes)?

View 4 Replies View RelatedI have been using a TP-Link WR1043-ND for a while now. It is configured as a dumb switch with DHCP disabled. Every other day or so, the device stops taking connections and I cannot access via the IP address. A simple power toggle resets everything immediately. Through this, the LAN connected devices never lose connectivity, I simply am not able to connect wirelessly or access the router via web browser.The only device I connect to the wifi is my phone, so it may actually be more frequently and I do not notice due to my low utilization (and I have 3G so I don't always notice right away if I'm connected). I have a WDTV Live SMP connected to one of the LAN ports and that functions non-stop regardless of the wifi. When the wifi is "down", my phone can see the network and attempts to connect. Sometimes it times out, other times I am repeatedly prompted that the password is incorrect, even though I am POSITIVE that I am entering it correctly. Once I toggle power on the router, the phone connects fine with the stored password.
I have updated to the latest firmware (about a month or so ago): Version: 3.13.12 Build 120405 Rel.33996n My hardware version is: WR1043ND v1 00000000 The router is connected (via LAN port 1) to a wall drop. My upstairs roomate maintains the gig switch and modem, as well as handling the network admin. I simply am using the router as a switch to provide extra ports and broadcast the network over wifi in my apartment.All that said: I need troubleshooting this router and it's configuration before I consider buying a more expensive replacement (and if I go this route, I might add a small switch as well to give me more than 4 LAN ports to work with). I am also considering flashing to DD-WRT before replacing as well to see if that makes a difference in reliability and uptime.
determine whether I have QoS properly setup on my router, and why the rules do not appear to be taking effect.ISSUE We have a couple of laptops, smartphones, and a Wii on our home network. One device, my roommate's laptop, is a real bandwidth hog. It's connected (via internet, not VPN) to a work server and is frequently downloading and syncing large datafiles and media files.Unfortunately, when that laptop is downloading the other devices either cannot connect to the internet without timing out, or is VERY slow, for example pulling up websites like google.com. When that laptop is offline, everything works fine. It seemed like enabling QoS would resolve our problem.\
SETUPLinksys E1000, latest firmware (v2.1.02), using WPA2-Personal security.
We first tried enabling QoS and setting the MAC address of the downloading laptop to "low" priority and all others to "medium". No luck - the downloading laptop still seems to be hoarding the bandwidth.We also tried adding the download application to the list and setting the port to "low". Still no luck.We added a new application called "web" and set port 80-81 to "high", but that didn't work.We then disabled WMM support. No dice. The other devices still can't connect while my roommatte's laptop is syncing.We've fiddled around with the settings a bit, but no matter what, it looks like the QoS rules are not being applied.And is it acceptable to have multiple categories (MAC and application) in the QoS rules?

View 4 Replies View RelatedThe issue is occuring on our local LAN where my ARP requests are being modified after a period of time by the router for one host. I'm finding that the host will work fine with the correct MAC IP pairing for a period of time and then about 15-30 minutes later, the arp table is changing so the associated mac/IP address is now the mac address of the router interface.
The FastEthernet 0/1 port has no ip proxy-arp enabled and is set with ip nat inside.This only started happening after restarting the router, however the running config was saved as the startup config prior to the restart.I've tried hard-coding the entry with the command arp 10.15.4.190 c82a.1459.0579 ARPA however that is not working as expected.
The device is an 1841 ISR with the advanced IP Services bundle loaded. Is there some way that the router is viewing my host (provides DNS, Directory Services) as a intrustion attempt and somehow rejecting the packets?

I show up at this business. They have about 40-50 systems. They have a 2003 AD server with a router, and 4 switches. There is also a dvr system on the network for cameras. Each switch is daisy chained together. Everything is working correctly except for the fact that the network drops about 5 times a day. Before they called us, they would just unhook one switch and plug it back in and it would work. At first, we took that switch and exchanged it with another switch in a computer lab to see if just the computer lab goes down. If it did, then that switch was bad. That wasn't the case, the whole network still went down. We had already left, but when we go back, our first choice will to see if there is a loop anywhere within the switch that will flood the network. Then, we were going to see if there was a switch that was getting a lot of traffic on the network to try to track it down. How can u monitor the bandwidth on the switches? They are 24 port switches. The switch is fs750/24 switch.
