High latency issue When connected through Wifi

Hi
I have configured wlc 2504 with cisco 3600 ap .when i connected my laptop wlan on n range,i tried to ping with my network devices am getting high latency 130ms,150ms
Can anybody provide solution for this

Hi Veeramani,
There are actually a lot of different factors that can go into high latency type problems on your wireless deployment such as co-channel interference, interference from other wireless devices, and overall utilization on the AP/Channel. With that said, there are a number of questions that need to be answered:
1. Is this issue isolated to either the 802.11b/g 2.4Ghz, the 802.11a 5Ghz, or both bands?
2. While associated to the Access Point, in the Controller Web interface, navigate to Monitor > Access Points > 802.11a/n or 802.11b/g/n(pick the band your client is associated on) > Find the Access Point and scroll to the far right. Hover over the small blue box and select 'Detail'. Find the section labeled 'Load Statistics' and let me know what you see as the Channel Utilization percentage as well as the 'Attached Client Count'
3. Since you have a 3600, I am assuming you have CleanAir enabled on them. Navigate to Monitor > Cisco CleanAir, and see if you can pinpoint any noticeable interfering devices with high % Duty Cycle

Can my iphone "attack" the company server when connected through wifi?

I've been told by my network administrator to stop connecting to the office wifi cause my iphone was attacking the server. He also asked me to install an antivirus which I did (iSafeGuard), ran it and nothing was detected on my iphone. I have a feeling they don't want us to connect to the wifi (since it is mainly for personal use), but they are telling me that the reason is because my phone is compromised. I'm ok with not connecting, and would have if they had asked me not to; but I think they are just pretending that there's something wrong with my phone and that it is attacking the server. Can anyone clarify if that's possible at all!? And if yes how can I make sure that my phone is not compromised. Thanks.

Your network administrator is an idiot as there are no viruses that run o iOS therefore no antivirus software is needed.
Unless you jailbroke your phone it is not compromised.
Ask them to show you proof in their logs and packet monitoring that your phone is causing a significant amount of network traffic.

Time Capsule high latency (ping) when using WDS

Hi!
I have this WDS configuration.
An Airport Extreme 802.11g connected to my cable modem as WDS main
A Time Capsule as WDS remote.
Both are using channel 1 with WPA/WPA2 Personal.
I can access the Internet. Printers and AirTunes work fine. But I have some high latency when pinging the ISP modem on 10.0.0.1 from any device connected through the Time Capsule.
More specifically when I am connected to Airport Extreme 802.11g the ping looks fine: within 1-10 ms. Both if I am directly connected to the Extreme with a cable or wireless.
BUT when I am on Time capsule (both wired or wireless) my latency time looks very awkward ranging from 1 to 1500 ms.

All packets get there but they are terribly delayed causing bad communication while using Skype or SIP telephone from my laptop and imac when connected through the Time Machine.
I have tried to change the multicast rate on both of them but with no success... still bad latency
Do you have any suggestion?

I have found the solution.
I post it here so it might help someone.
The issue is: even if you are in WDS don't use the WAN port in the Time Capsule.
Leave that one empty and use the other 3 LAN ports... and it will make your Time Capsule work perfectly!
The weird ping result in my previous msg were produced by a computer connected into the WAN port on my TM set into WDS. The port works and behave as a LAN port actually but it's not working properly. Avoid using it!

Snow Leopard - Latency issues when waking from sleep

I own two macs ('09 mini and unibody macbook), both of which connect wirelessly to an airport extreme N router. Since upgrading to Snow Leopard I have been dealing with terrible latency issues when the computers wake from sleep. Ping times from local servers increase from around 23ms to 220ms and webpages load slowly. A quick reboot solves the issue. Connecting directly to the airport extreme with a patch cable also solves the latency issue so I know it's just with wireless.
Has anyone else experienced this problem since upgrading and, if so, what are you doing to solve the issue?
Edit: Samples of ping times...before and then after a reboot:

I use Ethernet so I cannot comment but have you tried trashing the airport pref.plist and removed the preferred networks in the network set up in System Preferences and then set up the wifi connection again?
This seems to help with a lot of airport problems on this forum.

High latency issue of an evening whilst gaming.

Hiya`s Peeps, Having recently switched to BT from Virgin (this being only my third day as a customer) as the VM service for gaming in my area (Sth Manchester) on thier 50mb package was simply not viable due to over utilisation issues, I now find myself experiencing high latency issues with my BT service.
All three evenings have been lost to me as my in game latency (World of Warcraft) has rose upto 3500ms with occasional disconnections.
Also strange was that was after the BB was first switched on I had a consistent in-game latency of 24ms home and 24ms world, this lasted around 8 hours until I experienced my first lag spike, I was disconnected and when I eventually was able to get back in game, some 20 minutes or so later, my home and world latency had changed to 42/45 (still playable ) but every 10 to 15 minutes the world latency would again rise to around 3k and above and I would again be disconnected from the server.
I do apologise for the lack of any technical detail within this post as I simply do not understand such and struggle terribly with it, I am very happy with both my speed and ping tests, both being excellent in comparison to that that I would see when using the VM service.
What I am after I guess is advice from the community on how to get the best from BT bb for playing my online game, this connection is only used for World of Warcraft and very light reading on the www, I do not have a phone connected to this line and use no wireless connections with it at all, this PC (hard wired) is the only contraption connected.
Any help and advice will be greatly appreciated, Thankyou
Les

welcome to the forum
there is a 10 day training period after your connection is activated during which time you need to leave the router connected with no manual resets. The router may reset (often) during training but that is normal as the equipment in the exchnage tries to find the best stable connection for your line.
after the training period is complete and you have a stable connection then you can get the latency changed to 'fast' if yours latency is 'interleaved' changing to fast can make your line less stable than interleaved but it is the choice of gamers

Hello All Who Read This!
I just bought an iPhone 5 on the 21st of March. I ate through 850 MB's in 12 days. I read up on the issue of data consumption looking for tips to conserve data. I did not know there was a problem.
This morning I found out that I was leaking data very little, but daily it accumulates. I am in Barcelona, Spain. I do not have a contract, I am on a prepaid Yoigo carrier.
I happened upon an article/blog by Robert Parks at snnyc.com "problems persist in ios 6.1.2.".
Although his situation did not relate to me, I tried a few tests on my own to see if I could stop the data leak without turning off my celular data and possibly push notifications, I think I found a solution that might help someone:
In ios 6.1.3 goto Settings/Mail, Contacts,Calenders and scroll down to Calendars and turn off " New Invitation Alerts" and also turn off "Shared Calendar Alerts".
My Cellular Network Data seems to be behaving. I only see a change in MB used when I open an ap that uses data.
All The Best

Since the last update for my Iphone 4s i dont get text messages when connected to wifi. my wife is getting them. Imessage is switched off on both phones.

since the 6. version update. of my Iphone 4s My wife was getting my text messages. I found the problem was caused by Imessage when connected to Wifi. I deactivated Imessage on both phones to solve the problem. I now have updated my Iphone to 6.1.1 and i dont get text messages anymore. I have Imessage deactivated on my phone but my wife is getting my text messages again. my wifes phone was not updated to 6.1.1 because the last update lost all her contacts from her phone and we had to but them back in one by one from the outlook list. Her contact are listed in outlook on a seperate list to mine but we can only get my contacts download to her phone. We use the same laptop to sysc phones.
My Iphone does not download photos to My Pictures anymore. I have to copy them across to a folder. I cant find where it backs them up to.
I have lost all confidence in Apple now as i was forced to update to 6.1.1 because of 3G reception issues and not reciving calls and now back to spending several hours trying to fix my phone to recieve a basic text message.

Are you and your wife sharing apple id?
If you are that is the reason why she is seeing your imessage.
On both phone go to settings - message - send&receive - make sure the cell is the default.
You will have to uncheck or remove the apple id.

Since upgrading to Mavericks I am finding that I am lucky to get 2 hours (when connected to WiFi) of use from my macbook Pro.

Since upgrading to Mavericks I am finding that I am lucky to get 2 hours (when connected to WiFi) of use from my Macbook Pro. I have turned off Bluetooth ( which was not an issue previously), uninstalled Chrome, again not an issue before I upgraded, and have not seen any improvement.
I was using an older OS system (Snow Leopard) on my 2010 Macbook Pro. I am wondering now if the upgrade was an unwise move?

jbuckworth,
which apps do you run under battery power? Are any of them identified as “apps using significant energy” when you click on the battery icon in the menu bar? If you have a 15-inch or 17-inch model, are your apps using the discrete GPU (which consumes more power than the integrated GPU)?
How many charge cycles has your battery accumulated?
How long have you had Mavericks installed? Is Spotlight still reïndexing your boot drive? (It does that whenever your OS is upgraded, because so many files change in an OS upgrade.)

Third Party/Android Apps Cant access Internet when connected through Data Network

HT4914 why do some songs grayed out and only available when connected on wifi when trying to stream on iphone?

why do some songs grayed out and only available when connected on wifi when trying to stream on iphone?

I had this problem too - of grayed out music I could only play when in WIFI. I noticed when looking in iTunes, these grayed song were not chosen by me to sync on to my iPhone. They were stored in iCloud. I went to Settings > Music and then turned off "Show All Music" so only music that has been dowloaded to my iPhone will be shown.
I don't have iTunes Match, so you may have a different issue than what I had.

Mail only sends messages when connected to WiFi? Hmmmm.

Hi. I've got a POP3 email account that I have to set up manually. For some reason, emails can only be sent when connected to WiFi but not over a cellular data network. Anyone got any ideas? I can receive mail fine through either WiFi or Cellular Data Network.
Many thanks,
Max

Do you have a wireless network at home and Is the email account provided by your internet service provider associated with your wireless network?
Most, if not all internet service providers block the use of SMTP servers that are outside of their network or not provided by the ISP being used for your internet connection at the time unless the SMTP server is authenticated. The same applies when connected to the internet via the cellular network. Recieving is not a problem regardless the ISP being used for your internet connection at the time.
If the email account is provided by your ISP, most ISPs do not have an authenticated SMTP sever for the email account they provide.
Both my email accounts have an authenticated SMTP server and I've never had a problem sending with either account regardless the ISP associated with a wi-fi network I'm connected to at the time or when connected to AT&T's cellular network - for 2+ years aporoaching 3 years this July.

BIS WON'T CONNECT THROUGH WIFI

So my phone got wiped, lost everything. When i started to set everything up again (wifi etc) i noticed BIS does not connect through wifi anymore. It did before my phone got wiped. Is this temporary or do I need to do some fiddling around?
Thanks.

Hi,
When using your VPN are yo using Terminal LIcense or Remote Desktop Connection?
Please do the following to save form settings:
1. Only 1 module should be open when using form settings.
Close other modules that doesn't need.
2. Close the module after changed. To make sure the settings are saved.
3. Always close all the module before exiting SBO program, use the click FIle and Exit habit.
4. Terminal Licensing should be use when connecting remotely.
Thanks.
