My laptop is an ideapad U430 touch with, Intel(R) Wireless-N 7260
Same problem with Samsung Galaxy S4, ipad, apple laptop etc...
Most devices we tried are 802.11n and are fairly new / recent models.
Signal strength usually shows 4 to 5 bars. Looking at Wifi analyzer on my Galaxy S4, it shows -50 dBm standing 6 feet away. When I am 6 feet away from the Time Warner box (wifi enabled) it is like -30dBm or in my house close to my FiOS actiontech modem I am also like -30dBm
Are there any common settings that are recommended to be changed from defaults? I know evey environment is different, just wondering if there are any settings that most commonly changed on the WLC 2504 for performance tweaking...
Ok, we're getting somewhere. According to the Intel website, this card is a 2.4 Ghz (only) wifi card with 2 spatial stream. According to the website, the latest firmware for this card is version 17.0.3. I would strongly recommend your wireless NIC gets loaded with this version as previous firmware (like the 12.X), there were huge stability and performance issues.
I'd upgrade the firmware first before proceeding any further.
It is prefeeres to go with the latest WLC version as well as
Problems with bridge performance are the most difficult to troubleshoot because there are so many variables involved. In the case of wireless products, the majority of variables are literally invisible. Bridges have tools built into their software that can help to accurately determine the cause of symptoms of poor throughput, but they might not be able to solve the underlying problem. As a basic approach to troubleshoot this problem, you can increase the transmit power on the non-root bridge. Also, if the distance between the root and non-root bridge is less than 1km, you can set the distance on the root bridge to 1. Therefore, an increased throughput can be obtained.
Remember that the IEEE 802.11b protocol specifies 11 megabits per second, half-duplex, wireless communications. Set your throughput expectations accordingly.

This is the start of a display filter cross reference between Wireshark and OmniPeek.
The 1st installment is a table of advanced filters. More filters will be added as time allows.

I have created a Powershell script to automatically add a Wireless Guest User on Cisco WLCs. (tested on 2500 Series)
The script should be completely self explanatory.
