Ok, success. I think that I've figured this one out on my own and gathered some very interesting info. I've now tested with a laptop featuring a Broadcom BCM943228HM4L 2x2 wifi chipset connecting with m15 data rate (writing to its fast SSD) and was able to achieve max 34Mbps but here's the interesting part, when I enabled Clientlink, that value shot up to a consistent 70Mbps transferring a 50MB file from FTP. On the iPad it's around 40 or 50Mbps too now. Everywhere online it states that Clientlink 1.0 is only supported on 802.11g clients connecting to this series of AP, however I now believe it must be Clientlink that also enables MIMO for 802.11n clients (unless it is Clientlink 2.0 on this AP??). It's enabled by default in a WLC but not standalone. Maybe someone from Cisco wants to comment on this info...

Hi Leo, I know about that document but I don't believe that's the reason in this case. Reason being is that I've had this router do 74Mbps inter-vlan routing with NAT enabled.

Hi, I have a C887VA-W with integrated AP802 (equivalent to 1140 or 3500 series AP) supporting 2x3:2 configuration as far as I know. I'm doing speed tests from a wired FTP server on the LAN to an iPad Air 2 using 802.11n 2.4GHz. I can see the iPad associates with m15 data rate so that indicates that 2 spatial streams are used. When doing a file transfer I can only get it as high as 26Mbit/s downstream to the iPad and similar value upstream. I also tested with iperf and got the same result. I'm pretty sure the speed needs to be higher in the order of at least 70Mbit/s with 2 spatial streams on 2.4GHz What is the problem? *Please see ap config attached.

I'm not from the UK but another thing to mention is if they enabled the G.Vector standard on the DSLAM (aka ITU-T G.993.5) then the modem firmware needs to be 38h or above to support it. IMHO, I would just grab the latest firmware they have out since it will have all the latest features and optimizations plus a host of bug fixes picked up along the way. If it turns out to be worse just downgrade.

Hey, You probably fixed this by now but I notice that you're using the embedded DSL firmware that comes with IOS. According to the output from your sh controller vdsl 0 Firmware Source File Name (version) -------- ------ ------------------- VDSL embedded VDSL_LINUX_DEV_01212008 (1) Modem FW Version: 130205_1433-4.02L.03.A2pv6C035j.d23j Modem PHY Version: A2pv6C035j.d23j Vendor Version: Ap6v35j.23j 68 You can actually source firmware updates from the Cisco downloads page and set it up to use the new firmware bin file instead. If anybody else is having this issue that's what I'd try first as the embedded firmware is known to have some issues according to my research.
