Let's be honest now.  3800 supports mGIG.  This is Cisco's "selling point" to on-sell the 3850 with mGIG.  Going down the "wave 2" bandwagon is very expensive.  Unlike previous upgrade, like from 802.11 a/b/g to 802.11n, it was as simple as replacing the AP.  That's it.  For these wave 2 models, one has to swallow hard.  Not only do one have to replace the AP but to ensure that there is enough bandwidth from the switch all the way to the core and WLC.  10 Gbps and 40 Gbps backbone are mandatory. Those things are not cheap either.   So to go down the wave 1/wave 2 fad, it may be necessary to upgrade the access, distro and core switches.  Distro and core must have ample 10- or 40 Gbps optics.   ...

I'm very familiar with this NIC card because our office laptops have this.   This NIC (I think this is even hardware revision 0) is only 2x2 so whatever speed you're seeing now, that's it.  You've hit the limit. The wireless NIC driver is very, very old.  I'd upgrade that first.   Next, if this laptop is being used in an environment where there are a lot of APs, there is a settings called Aggressive Roaming.  The default value is "2".  My recommendation is to crank this up a notch to "3".  Do NOT try any higher than this.  This won't bring the speed up but it will make roaming a lot better.   ...

Can you please remove 6- and 9 Mbps Data Rates? What kind of wireless client are you using? If Windows-based, what is the wireless NIC and exact wireless NIC driver? ... View more

That looks like a cable problem. Is the switch capable of performing a TDR? This is the consequence for doing the forum without coffee in the morning ... misdiagnosed.   ... View more

@bhupenderrawat79 wrote: So in your opinion it will be better or best practice to use 40MHz channels with 5GHz only correct?  I would prioritize 40 Mhz channel width, HOWEVER, this will depend on the worst wireless client.  If there is a wireless client that won't talk in 40 Mhz then crank down to 20 Mhz.   @bhupenderrawat79 wrote: and now lets say my clients laptop can support 2x2 MU-MIMO which means if i am understanding correctly the theorical speed that my client could get, would be 433mbps I would say 300 Mbps half duplex or 150 in a single direction.   ...
