    Bluetooth drivers from Intel still hasn't been updated yet. Just keep visiting Intel every week for a new release. Hopefully they release one soon.

    Need to correct: 801.11 ac performance still is capped at approx 100 Mbps, measured with iperf. File copy at approx 9-10 MB/s. Wireless properties show up to 866 Mbps though. Went back to the Sager drivers.

    Did some more testing and apparently I was wrong in my assumption that the antenna is low performance on 5 GHz. When I have AC power switched on, the reception on 5GHz is ok. When AC is disconnected, the reception gets much weaker. There are locations where I see the receive counter in the wireless properties stopping as soon as I unplug AC. When plugging AC in again, the receive counter continues. Obviously, no AC = no reception.

    Unfortunately I didn't test this with the previous 6235 card so I cannot tell right now whether this is any issue with notebook or with the specific 7260 ac card. Anyway, I was wondering if someone has noticed such behaviour before?

    For completeness, on 2.4 I don't see this behaviour.

    Cheers,

    Thanks WhatsThePoint. Before I was getting frequent lag spikes, didn't know if it was the router or the card or both or what. These seem to have improved it. Lag spikes still occur just not as often. I hope another driver update will eliminate them completely.

    Just updated to the *Official* 16.1.3.1 drivers from Intel. No difference from the 16.1.1.3 so far.

    Thanks for the tip. I prefer to install drivers only so all I did to revert back to my previous settings was to change the channel width of 2.4 GHz to "Auto" and left the rest to the "defaults." Overall, this Intel 7260 series is really good since I haven't had any issues with it unlike the Centrino series.

    I have the Intel settings enabled>5ghz band>AP MAC address and Cisco option enabled

    OS = Windows 7 x64 HP

    inSSIDer still hasn't been optimized with an 802.11ac setting

    Well, from your inssider screenshot you only have a few routers/access points. Look at how much routers/access points I have to deal with. I'm amazed I don't get crazy speed drops at this much congestion (router is only 2.4 GHz) at all though the link speed occasionally dips down to 78 MHz when there's too much interference from my neighbors. At least it's not like my previous Centrino Wireless-N 1000 where the connection drops every few hours. I don't know why inssider reports 156 Mbit instead of 144 Mbps like on the other Wi-Fi adapters such as Broadcom or Ralink.
