Wireless :: IPhone Taking Down Network?
Apr 13, 2012
Mobile 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))?

I have removed all port forwarding and enabled DMZ? I made sure the DMZ IP matches my internal IP. DMZ still not taking effect. One thing I noticed is that when I visited [URL] it showed a different IP then what was assigned to my router itself.
Modem > Linksys Wireless > Computer
Should the Linksys Wireless be in gateway or router mode?

I have a Dell laptop running Windows 7. 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.

I have an Inspiron 1521 and while I can find and connect to a network easily and quickly; it takes 5 minutes or so for it to really work. My icon says it's "identifying the network". Is there anything I can do to speed up this process?

I log onto other wireless networks the first time by inputting their passwords. My iphone then always automatically reconnects wirelessly to them without have to input the password again. The phone can be asleep for a few minutes or I can be gone for a month. The phone always automatically remembers & reconnects to these networks.However, it doesn't work that way with my d-link system @ home. Everytime the phone sleeps and I wake it up, the wireless connection is lost. There is no automatic reconnection. I have to input the password each time in order to re-establish the wireless link. My printer and laptop seem to stay connected. d-link settings I need to change in order to get my iphone to automatically connect all the time?

I cannot get my iPhone 5 to access my wireless network (Linksys E4200) since I reset the router. It asks for the password but doesn't accept it. I'm a newbie so be gentle with me! MSZ

I had PCs, Macs and other devices (iphone, itouch) able to connect fine to the WRT610n. I moved to an apartment and when I turned the network on all the devices could connect expect for the iphone and itouch. I have tried turning the wireless security off and MAC filtering off . I get the same "Unable to join the network" message.

I have a Linksys WRT120N which had suddenly and unexectedly stopped working after disconnecting my roku box. I didnt worry about it until I got an Iphone and now .I was able to re-establish the wireless connection on my netbook today after a ton of research and messing around with the settings and then downloaded network magic, which finally fixed the problem. I believe that it automatically transmitted the WEP key to the Netbook, which is what I am missing when I try to log into the network on the Iphone.How do I get this password to show up on Network Magic? When I look at the settings, it does not show the actual numbers, they are hidden.

Set up our E3000 following the set-up guide. However, wireless devices (laptop, iPhone) recognize the network, but cannot connect. There's no prompt for a password or anything.

My EA4500 router seems to drop mine and my wife's iPhone wifi connection at what appears to be the edge of my router's range. When we come back in range, our iPhone's intermittently give the error "Unable to join network.". And we're stuck in that mode. When I check the Devices menu in the CCC interface, I notice the iPhone device is configured and still online. However the "x" box to delete the device is greyed out because it's online. So how do I get out of this state and have my iPhone connect

My 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]

Currently using a netgear WG602 wireless router which i use to connect to my 2nd PC and Iphone, with the Netgear router running from my main PC.I have recently been having trouble with my 2nd PC ad Iphone randomly losing connection and the only way for the connection to be reastablished is to reboot the wireless router. Once rebooted i am able to connect again to the internet with no problems, interestingly enough my main PC never loses connection. Also sometimes when i lose my connection and reboot the wireless router i will have a IP conflict pop up on my 2nd PC however i would i say i get this once in every 10 dissconects and not all the time. Sometimes i won't dissconect at all in a day but sometimes i may dissconect 5-6 times.

Camera set up with the Beta Mac wizard connected via ethernet on Airport base. Wireless security WPA2 Personal. Using DHCP. AirPort Utility 5.5.2, OSX 10.6.6.I can see the cam with the myDlink Lite iPhone (4) App when I am in my house with my wireless network. When I am out, away from my network, the App can't connect to the cam, tells me to check my network settings. I did the wps way and added the cam in the airport base utility *Access Control* tab but still doesn't work. Checked in the cam web page settings, can't figure out what the Pre-Shared Key is and where I get it/set it up in the airport utility...

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?

I have configured some iPads and iPhones to Connect to an ASA via AnyConnect (ASA 8.4(1), iOS 4.2.1, AnyConnect 2.4.4009).I have configured the devices with the "iPhone Configuration Utility" (iPCU 3.2.0.267).
My question is: How to configure the "Network Roaming" feature of the AnyConnect via the iPCU?I can configure everything else correctly with the iPCU (server, certificate, connect on demand, proxy settings,...) but as mentioned NO network roaming!

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?

We'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.

It is good at times but usually it gets slow and web pages come up with "The web page is taking too long to respond". When I run Diagnose, sometimes I get the computer is correctly configured, but something is wrong with the DNS server (I dont know what that is). I have a NetGear CGD24G Wireless Router that was supplied by Charter when I got internet from them again. I also run Windows 7.

Past couple of weeks trying to connect to some websites. It is only SOME, not all websites. It will either say that it is taking too long to connect or that the website is experiencing problems. I have no idea where to start as i am pretty clueless when it comes to configuring/repairing network related issues.

So 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
