I appreciate the offer to help, so let's see if we can fix this.
I am running 5 wireless machines, 4 running on Windows 7 and 1 Mac. They all test at approximately 9Mbps download, .9Mbps upload, ping rate between 5-8 ms, and the furthest machine at 88% signal strength. We currently have a 2.4 GHz phone system, a wireless alarm system, and are using the new Logitech 2.4 GHz mouse/keyboards, so that is a reality we have to deal with.
Our wireless network is configured as such
- Use Unicasting
- MTU -1500
- Mixed 802.11 b.g.n mode
- Wireless Channel Channel 1 ( i've tried 6 and 11 as well)
- Transmission rate- Best (Changing to MCS 14 or 15 will not allow wireless connection))
- Channel Width Auto20/40.
- QOS Disabled
- Enable SPI
- Transmission High Beacon Period 100, RTS and Fragmentation 2346
- Enable WISH on
- Priority Automatic - Off
- Wi-Fi Protected Enabled
- Enable UPnP Off
- SecureSpot Off
Anything I'm missing?
