    EAP110 wireless compatibility issue)

    Model :

    Hardware Version :

    Firmware Version :

    ISP : [/COLOR]

    Following on from here http://forum.tp-link.com/showthread....TV-and-hotspot - I have run into a really weird issue that I have never seen or heard of before

    The last mile connectivity is between EAP110 and a set of Hikvision wireless cameras (2CD2020F-iW)
    For some odd reason, the link between EAP110 and the camera just refuses to work as expected.. While the camera does connect to the EAP110, the connection is completely unusable with over 80% packet loss even on ping

    What's weird is that the same Hikivision cameras are happy to connect to multiple other access points I tried on my test bed (Netgear R7000/Linksys WRT54G/TP-Link Archer C7/Xiaomi Router) with a stable throughput

    Similarly, every other client I tried with the EAP110 seems to work without fuss (surface laptop/Macbook/couple of iphones/android phones and even a Dahua IPC wireless camera)

    It's just that the two of them refuse to share a stable connection even when placed next to each other

    As a last resort, I tried connecting the Hikvision camera wired to an old TP-Link MR3020 in client mode (connected to the EAP110) and EVEN that works fine!

    However the EAP110 and the camera just won't work together - I tried all possible encryption combinations and even an unsecured connection but the two just won't play along

    I have a total of 10 cameras and 4 EAP110s lying with me now.
    Short of ordering 10X client mode devices and IP66 boxes to house them in harsh outdoor conditions (and the associated wiring paraphernalia) , is there any other thing I should try?

    Strange. Since you tracked down the odd behavior with the Hikvision camera to the EAP110-Outdoor already, I suggest that you open a ticket at TP-Link's tech support. You could also contact Bob from TP-Link Tech Support Team by PM, who did post in the GC-Wifi-for-CCTV-and-hotspot thread, too (see post #7).

    Ok.. Dropped a PM to Bob and opened a ticket at TP Link support
    Here is a screenshot from the EAP if it helps

    The 1st client is a TPLink MR3020 in client mode (Notice the Data rate)
    The 2nd client is the Hikvision camera (Data Rate - 0)

    It appears the issue is with the WMM settings in QoS on the EAP
    By disabling WMM, the data rate has gone up to 54mbps

    Will post back after testing

    Edit: it was indeed an issue with the QoS (which for some odd reason is enabled by default)
    Disabling the QoS has resolved the issue

    Disabling the QoS has resolved the issue
    Ok - Not really a solution..
    I confused WMM with QoS
    While disabling WMM fixed the connectivity issue, it also limits the EAP110 to 802.11g only

    There seems to be a serious bug with the EAP110 firmware then as the camera plays fine with both a netgear r7000 and a Archer C7 with WMM enabled
    However the data rate drops to zero the moment I enable WMM on the EAP110

    With WMM enabled on EAP110

    WMM is indeed a sort of QoS for wireless frames (IEEE802.11e).

    Could indeed be a bug if the cam works with Archer's WMM mode. What's more, I wonder why fixed 802.11n mode requires WMM (should not require it IMHO).

    Let's see what TP-Link Tech Support finds out.
