Cisco :: 5508 - IPhone Drops Back To 3G When Wireless Available
Sep 20, 2011
We have Cisco wlc 5508 and cisco 1252's.
I have a SSID as WPA2(PSK).
The problem is, when an iPhone joins on the wireless, it only holds the connection for a short period of time, then reverts back to 3G.
I've already tried; disabling/re-enabling Aironet IE, Disabling/re-enabling Client Load Balancing, Disabling/Re-enabling Client Band Select, changing to G only, changing supported speeds up to 12Mbps and disabling lower ones.
I have the WRT400N router and using windows 7 (on this computer). It works perfectly with any computer I use in the house (there's 3). As soon as I open a laptop, its connected. My iPhone (we have 2) and an iTouch, are a different story. They connect, stay connected sometimes for 5 minutes, sometimes 5 hours, then will drop the connection out of nowhere. It doesn't matter how close or far I am from the router. Sometimes I'll get a message that I have an incorrect password (which it's not, which is why it DOES work). Sometimes I don't get a message at all (on the phones I'll just notice its on E/3G). Now, looking through the database I noticed there is a program for the valet routers that lets you add the phones, yet this doesn't apply to mine.
The tech in live chat told me it was the phones. I know its not as I had a wireless modem before this, and I never once lost a signal or had it ask me for an incorrect password.
We are implementing a new corporate wireless network with Cisco 5508 WLC's and C3602I LWAP's. We are not running any RADIUS or EAP at the moment and are starting with WPA2 w/ AES with a pre-shared key to begin piloting. The issue we are having is iOS based devices (iPhone/iPad) do not seem to want to connect. We just get a could not join wireless network messages. We have had success with several Windows based laptops, my MacBook connects, as well as several different Android devices.Looking at the logs on the WLC I see these entries which correspond to the MAC address of my iPhone.
*apfMsConnTask_6: Jul 17 17:25:20.620: %APF-3-CHECK_SUPP_RATES_FAILED: apf_utils.c:376 Could not check supported rates. Missing Supported Rate. Length :0. Mobile MAC: 24:ab:81:92:4d:97.
on a 5508 WLC can we create new SSID for I PAD / IPHONE Users without having ISE, only I phone / I PAD are allowed to be authenticated rest all should be denied. IS this possible?
Guestconnect SSID configured on 5508 WLC with Pass through athentication (NAC guest server). No issue with Laptops and Iphone/Ipad ver 4and 5. Only Iphone Ver 6 users unable to access Guest connect .
We have a centralized WLC with some branch office with AP's in Flexconnect Mode. The Wlans are configured to use Web Authentication (Landing Page). The Landing Page is Cisco Default.
We're experiencing some problem with Apple Devices, on some the Landing Page apperars on some not. The WLC Software is about 1 year old. On a XP machine the landing page doesn't appear too, but you can type in the address manually and it works.
Whats the best solution to include the Apple Devices successfully in the WLC Wireless World.
I have 2 Cisco 5508 Wireless LAN Controllers.They are NOT connected to a WCS.Is there a way to configure the 5508's to send email notifications when an AP drops off line?Is not is this functionality available with either a WCS or new NCS?
I have a Cisco 8510msr that is connected back to back with a 7206vxr across a 155Meg connection.I receive lots of Output drops on the 7206vxr interface facing the atm switch. When I do the following command:-
kwdair9#sh atm int atm 1/0Interface ATM1/0:AAL enabled: AAL5 , Maximum VCs: 4096, Current VCCs: 27 Maximum Transmit Channels: 0Max. Datagram Size: 4528PLIM Type: SONET - 155000Kbps, TX clocking: LINECell-payload scrambling: ONsts-stream scrambling: ON797522 input, 881483 output, 203946630 IN fast, 223768062 OUT fast, 0 out dropVBR-NRT : 110288 Avail bw = 44712 <====
I only have 44megConfig. is ACTIVEkwdair9# I only get 44Meg of the available 155Meg.There is no QOS on the router and the only commands I can find that vaguely see that refer to QOS are on the ATM switch:-

I have two site that has a copper wire ( 2 wire) connection between each router ( No Telco in between ). Now I want to use 1921 router with HWIC-4SHDSL-E card to connect these two site together. Can I use attach configuration to make the connection reference from the diagram ?
I have 2650XM router and 2620 Router Both routers have built in WIC T1 CSU/DSU cards
2620Router --
2620Router#sh int se0/0 Serial0/0 is down, line protocol is down Hardware is PQUICC with Fractional T1 CSU/DSU Description: DTE side MTU 1500 bytes, BW 1544 Kbit, DLY 20000 usec, reliability 255/255, txload 1/255, rxload 1/255 Encapsulation HDLC, loopback not set
[code]....
My question is that cisco website says there are two type of cable connections for this type of config --which are --T1 CSU/DSU ConfigurationSet one CSU/DSU to clock source internal, and the other CSU/DSU to clock source line. The linecode, framing, data-coding, and timeslots must be set the same on both CSU/DSUs.Four-Wire 56k CSU/DSU Configuration For my network connection which type of config i should use??Secondly i try to connect these ports by normal crossover cable it did not work.So for this type of connection i know i need T1 cross over cable-- which has RJ 48 connections at both sides.I check cable from ebay which is RJ45 RJ48 cross over -- will this cable work in my router to router connection.
I have 1 2611xm router and 1 2801 router. For my own lab purpose, i want to configure them back to back to support voice services. I don't know what configuration will be required at each end. in 2611xm, i have NM-2V and its also detecting the card, so i hope it will work ? also what commands i need to run on both ends .
I would like configure two router (e.g. 1921) back to back via a 2 pin copper wire. Can I use HWIC-4SHDSL-E card to do it? What is the configuration I can use?

Just to get this clear as having issues with a E1 link with CRC's at one.Router A,Network-Clock-Participate WIC 1,Should router B have clock participate for WIC 1? We currently have controllers set as UNFRAMED but guess we can set to NO-CRC4 both ends and telco will pass this.
I'm looking for instructions on how to setup and connect two RV082 routers together with a crossover cable between their WAN ports. This is to connect two separate LANS together via an ethernet connection. For staging we are setting everything up with a crossover cable in our shop. Ultimately the crossover cable will be replaced by a microwave link between the two LANS several miles apart. There will be no internet connection.
securing a back-toback connection using E1.The connection is between two cities, using 2x CISCO 1841 router + VWIC-1MFT-E1 interface at each city.
The E1 connections has been provided by our local telco, and they are completely private. The customer is a bank, and they asking me if this is a secure connection or not. If possible, we need to guarantee that no body can get access to the bank network even if they brought E1 modem at one of the ends (telco PoP).
I searched a lot but couldnt find a clear document about connecting 2 G.SHDSL routers back to back.First of all I am not sure which type of cable (RJ11) is used for connecting two 878 routers. Does it have to be cross or straight cable.
Which RJ11 pairs will be connected each other [code]
According the configuration samples One router must be CPE and the other must be CO for simulating DSLAM.
I'm having some trouble getting two Cisco 888's to work correctly back to back.. The two routers will ultimately be used in conjunction with a BT EPS8 circuit which is effectively four wires short distance between customer sites. We have configured lots of these using the older Cisco 878's.
Anyway, as i've been struggling to get line sync on site I've gone back to basics and connected the two 888's back to back. However, I've found that no matter what I do I can only get the routers to sync at 384kbps!? And that's with a one meter RJ11-RJ11 cable.. Very strange. When we've used the 878's we get much more bandwidth. I have tried statically assigning the line rate at both ends but it still only works at 384kbps.
I am setting up my lab using two 2901 routers which is running on 15.2 IOS.I am trying to simulate a back to back BRI.BRI Module: WIC-1B-S/T-V3 (x2) one of each router.
I followed this amazing document to understand the concept of BRI and configuration. url..but it never says if i can use the module that i have mentioned.
Q1. What cabling i need to use to setup back to back BRI using 2x 2901 routers with these modules? Q2. What cabling do i need to use. Q3. Is it actually possible to use these 2 modules alone to simulate a back to back BRI..?
I recently attempted to update my access points Software from AP541N-K9_1.8(0) to AP541N-K9_1.9(2). As soon as the update and reboot were complete I could no longer connect to the wireless network using my iphone. I switched back to the secondary 1.8 software and could immediately reconnect my iphone to the network. Upgrading to 1.9(2) changes a setting or is flawed.
Since I have static ip I cannot use the printer Brither Model.I have U verse system from At&t and I have gotten static IPs to be able to install an IPcamara and to access it from any point in the world. But since I have gotten the static IPs I had a problem with my printer, also the i phone,and I pad do not connect to internet but the windows lap tops are working fine with the wifi.
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))?
My iphone 4s does not connect to my wireless network which runs on netgear wgr614 v7. It did until two weeks ago. On my phone it will not accept the password and I have not been able to connect at all. On my phone it shows the network is locked.
my wife and i can't connect to our home wireless internet with our new iphones. last night we tried connect a tablet we bought for our son to the wifi but it won't connect either.
I am testing our new wireless network using 1 Cisco 2504 wireless controller with 5 licenses 4 Cisco Air LAP 1142N Access Point I configured it very simple for testing There is only one interface and vlan is untaggetd There is also only one WLAN with one SSID Currently security setting is WPA + WPA2 + PSK (I also tested with no security setup) Wlan session time is diabled and controller user idle timeout is set to 1000000 (Max)AP boot version is 12.4.23.3 and ISO version is 12.4(23c)JA3 Problem is clinet(iphone) does not automatically associate with 1142N Access Point even after it learned network. Phone has to be authenticated again to connect to network same iphone can automatically associate with old 1220 Access point but not with New AP if I urn off and turn back on wifi from iphone, it does see the network but does not connect but I have to manually reconnect to it with password I want iphone to connect known network without reauthentication process after iphone's wifi function is turn on?
My mail will not open, says pass word is incorrect, how do I get this to change? I have wi-fi, and I deleted a bunch of old e-mails off of pc. Since I have done this, I can not get anymore mail sent to my iPad. Can you direct me to how to change this?
My wife and I both have Win XP laptops. For some reason, one day we both lost our wireless connection. However, my wife's machine later was able to reconnect - mine wasn't. My machine sees the wireless network, sends the key, and tries to acquire the ip from the router. That's where it gets stuck. The ip address never gets updated.
I use a tethered iPhone to access the Internet. We live outside of the DSL service area so this is really the only high speed internet connection I have available.Unfortunately the "wireless hotspot" feature of the phone isn't very consistent. I can get all of my computers to connect to my phone this way, but the connection is constantly dropping, and I'm always having to reboot the phone to get the computers to pick it up again. The most reliable way to use the tethering is to just plug the phone in to whichever computer I happen to be using. This does create a problem, though. If I want to print to the network computer or access a file off of one of the other computers I have to manually connect to the wireless router, because that's the only way the computers can talk to each other. In the meantime, though, I can't use the internet because my computer thinks it needs to try to connect to the internet through the wireless router, and when it can't find the internet that way it just tells me there's no connection. Nevermind that my phone is still plugged in, for some reason it doesn't want to use that connection if it can see the router.
I purchased a new E-2500 router and got it operating my computer, but my iphone will not log on, I set up guests and now it appears to log on, but doesn't.
IPods and IPads to connect to stand alone AP1131? My scenario is as follows:
There is a section of a campus that is covered by 14 stand alone AP1131 were I experience the problem. The security parameters are: 802.1x, wpa enterprise, tkip
The other section is under WLC also AP1131 but in this case in WLANs/Scurity/Leyer 2 I checked boxes:
Wonder if the fact that I chose WPA2, AES makes a difference with stand alone mode? Anyways I tried configuring AES in stand alone APs and it didn't make a difference since I could not connect either.
I have several WAP2000 (Firmware 2.0.0.5), and while they work fine for PC's, iPhones, iPod touches cannot connect to them.Well, they connect briefly, get an IP address from the router, and immediately drop the connection to re-connect again.I have tried changing channels, eliminating all but one of the AP's, and so forth. Any issues with this firmware? I see posts where people are saying their iPhones connect up fine. This happens on versions 3.x and 4.x of the iphone O.S. It's not limited to one iphone or ipod touch; we've tried several.
