Hi,<br />
<br />
I have a few Cisco 3850 switches and some 2600 wireless mesh access points. <br />
<br />
I few weeks ago I updated my iOS software to 03.03.04SE.<br />
<br />
Now my Windows 8.1 computers on WIFI all have very slow connections and drop off the WIFI every day. <br />
My Windows 7 clients work over WIFI with no problems. <br />
<br />
I've tried with different Windows 8.1 computers from different companies with no luck. <br />
All Windows 8.1 computers drop off the WIFI. <br />
<br />
I've disabled IPV6 because were not using it. <br />
I've tried different wireless drivers with no luck. <br />
<br />
Please let me know if you need any additional information. <br />
<br />
Thank you.

A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.

Switches / Hubs

Wireless networking is anything related to the transfer of data between two (or more) devices without the use of a physical connection, ranging from getting advice on a new Bluetooth headset to configuring sophisticated enterprise level networks.

Wireless Networking

The Windows operating systems have distinct methodologies for designing and implementing networks, and have specific systems to accomplish various networking processes, such as Exchange for email, Sharepoint for shared files and programs, and IIS for delivery of web pages. Microsoft also produces server technologies for networked database use, security and virtualization.
