    Cannot "Get GMT", error 5028

    Region : Canada

    Model : TL-WR841N

    Hardware Version : V8

    Firmware Version : 3.15.9 Build 140724 Rel.63227n

    ISP : Xplornet


    No idea when this started happening, but just noticed it when I was trying to resolve a timestamp problem with my media player that has been an issue for months. No updates to the router were made at that time, and the router is not being used as a bridge. It's directly connected to my broadband router via ethernet cable (WAN port).

    Under System Tools->Time Settings, when I click "Get GMT", the following error is returned:

    Error code: 5028
    Get GMT unsuccessfully, make sure that you have already connected to Internet.

    I've tried many different NPT servers, URLs as well as IPs, but always get the same error. Under System Tools->Diagnostic, I can successfully ping all of the NPT servers. My internet access via both LAN cable and WiFi work flawlessly with many devices (with the exception of this issue).

    Even though I'm not using it as a bridge/WiFi access point, I've also tried the static routing workaround suggested here with no success.

    I've also tried upgrading to the latest firmware (from 13050), which did not resolve the issue.

    Any ideas? I've been searching for days and haven't found a solution.

    It was working, right?
    Did you get a WAN IP address on web interface of WR841N?
    Did you reset the router to factory defaults and reconfigure it?

    Hello Woodsman,

    Could you explain why do you use the WAN port?

    Could you test a LAN port instead, with a special route for 2 NTP servers?

    Give us screenshot from Status tab of your router.

    Can't be certain that it was every working right. I just noticed it due to my media player issue, which had the correct date/time since I bought the router over a year ago. Yes, I re-set to factory defaults after updating to the newest firmware, then re-configured.

    This router has the following ports: 1 2 3 4 WAN. It will only work if the router is plugged into the WAN port.

    Attached. IP address is striked out because I'd rather not share that with the world.

    I can see that you have internet access by WAN port. Can you show us this error after GMT button click?

    Sorry I don't have this router here and I can't check it. Maybe it is some bug in firmware. My advice, you have to contact with TP-Link support and ask about it because I can see this bug first time.

    Will do, thanks for the effort anyway. This is frustrating

    I've tested on my Archer D9 and I don't have any problem with GMT

    Try to set the IP address of NTP server not the DNS !
    Show me the route you entered...

    I've tried this, as indicated in my original post. Sample IP: 69.167.160.102

    Starting to think my ISP may have started blocking port 123. I've raised the issue to them and will update this thread when I receive a response.

    You have to check router on another internet link without any blockades

    My ISP claims to not be blocking port 123, which sounds reasonable, as updating my OS time works when directly connected to the modem, but doesn't when connected via the router. Looks like it's a problem with the router.

    I'll contact TP-Link support.
