    So after a few days testing, it apparently works better. I set a fixed ip to the router and put his DHCP function to OFF (devices connecting to it get their IP from my broadband cable router).

    My wife didn't complained about no connection so we might have a winner here. In my end I sense micro drop of connection ( pages not loading be yes when refreshing etc...) i'll contin˙e monitoring and test putting the DHCP always on on the extender side.

    Same here. When viewing the logs connection log is continuously but it is workable. I'm disappointed but the cost to return it are to high.

    OK, I have a similar issue with an Archer C8 as my main wireless router and a RE450 as an extender.

    Initially, I have used a standard setup - with RE450 connected to the router via WPS, DHCP on the router side, DHCP off for RE450.
    The extended network was working ok for some time - from 30 minutes to a few hours - then it dropped and the only solution was tor restart the extender.

    A couple of days ago I tried to make some changes: RE450 IP changed to static, 2.4GHz channel width from the router changed to 40MHz (not auto).
    Result? Same behaviour as before - extended network dropping at random intervals, needing RE450 restart everytime.

    Both devices have the latest firmwares.
    Archer C8: 192.168.0.1, DHCP on (...100-...199), both 2.4 and 5GHz networks on.
    RE450: 192.168.0.2, DHCP off, extending router networks.

    Looking at RE450 logs I got some errors:

    In my opinion, feedback this to tp-link's support team may be a better choice.

  5. #20
    Well, I've tried but it seems like TP-Link support is pretty much useless, especially in analyzing such. Since they (TP-LINK) are facilitating these blogs, it is hoped that someone there is reviewing it from time to time. Hopefully their development team is paying attention to these major concerns.

    I confirm that enabling the DHCP on the extender renders it useless. With DHCP off it works so so.... Anybody from TP LiNK reading these forums? At least I would like to know that they are working on a firmware fix if possible.

  7. #22
    i'll try that and post back in a few day to let you guys know if it works.

    I had similar issues with loosing internet connection on the 2.4 Ghz network, but not connectivity to the extender.
    Out of desperation, I tried to disable the network connection between the RE450 and m router on the 2.4 Ghz network, and hey presto, now I can connect to the RE450 on 2.4 Ghz and 5 Ghz just fine.
    And with working internet.

    I guess this means that the RE450 <-> Router connection will only run on the 5 Ghz network, but that is fine with me.

    RE450 Range Extender losing connection

    Hi there. I have an issue when using a wi-fi range extender on my network. The station connects ok and all the modules work ok when just using a standard router. I have a dead spot for wifi in my kitchen when using the internet so i have set up a wi-fi extender to improve the coverage in there. trouble is when this is enabled the weather station fails to show any data and does not connect to the internet. The extender works ok with my laptop but seems to cancel the base stations connection to the main router....can any one help please?

    M-Ras, how did you disable network connection between your RE450 and your router only on over 2.4Ghz?
    Did I understood correctly that your router still broadcasts/extends 2.4 GHz SSID and your devices could connect to it on this band as well. Though your RE450 is connected to your router only on 5 Ghz band.

    Multi- and Broadcast connection gets lost

    Because I also have the problems mentioned I ran a series of tests. I use the RE450 to connect an Ethernet-only Mac to a remote Airport Time Machine. What I could see is this:
    • Point-to-Point traffic is fine (e.g. ping or http to a particular server)
    • Multicast or Broadcast stops working after one hour (e.g. DHCP or Audio/Video streaming)
    Point to point eventually stops working as well: Once the DHCP lease expires the Mac can't get a new IP address and terminates all connections.

    From what I have read, any wireless client negotiates a session key with the WLAN access point. At the same time, there is a shared session key used for Multi- and Broadcast. This shared key is renegotiated every hour for all connected clients. It looks like the RE450 does not properly refresh this key, even though it shows in the RE450 log that it does receive a new key every hour.

    Any news on this?

    I set up the TP-Link RE450 connecting it to my 2.4Ghz router, it works for about 5-10 minutes then suddenly I cant connect to it on its assigned IP.
    The wireless network it creates ( gave it a unique name to connect to it directly ) no longer lets any device connect to it. I have DHCP turned off so IP's are assigned by my router .
    I have a mikrotik router.
    Only thing that lets me connect to it again is a Hard Reset with the small button on the RE450

    Hello,
    I hope I can reply in this thread as I seem to be having a similar problem.
    Device: RE450 V1
    Firmware; RE450(UK)_V1_160727

    I have had the extender for over 3 months and it suddenly started losing connection yesterday. A restart helps but apparently only for a short while. Logs say connection timeout, DNS probing failed etc. All the lights are on. The router it's connecting to is a BT homehub 4 (I believe.) I will contact support, although from your posts above it might not be helpful.Really annoyed as it was working perfectly before.

    Am using the RE450 with the 1.0.0 Build 20161202 Rel. 56846 firmware.

    It's set up as a wired link to my modem. 5Ghz is working fine, 2.4Ghz has just disappeared completely.

    It says its functioning and pumping out the frequency, but no scans on any computer/smart phone show head nor tail of there being a 2.4Ghz network available to be accessed.

    Tried turning it on and off again.

    Just away to see if a reset will fix it, but don't really want to have to do that everytime that the network disappears on me.
