    Keep getting Default Gateway not found error


    Hi,

    I moved in to the new apartment and since the Wifi reception wasn't so great I asked the landlord to install a Fritz Repeater 600. Now I get the signals but every 5 mins I drop connection to the internet due to Default Gateway not found error. That never happened to me before ever and my system and the software all are same. The internet works if I either reset the Wifi, Plug/Unplug the repeater etc. but only for 5 mins. By the way, I have a desktop PC and I'm using TP-Link TLWN-725N as my USB Wifi Adapter.

    I know this is a common problem and there are tons of articles on it but nothing worked for me. I already tried:

    • Setting the power options to High Performance/Never allow Windows to turn this device off
    • Update the drivers (It automatically picked Realtek driver but I also tried by manually downloading the TP-Link driver)
    • Can't downgrade to 802.11g since n is the only option I get
    • Enable/Disable Firewall (I'm using ESET Internet Security)
    • netsh int ip reset
    • Manually assigning Gateway/IP


    I should also mention that I don't have root access to the actual Router as it's in another adjacent apartment so I can't really tinker with it much. Also I all my other devices work without any issues like my Macbook and Phone. It's driving me crazy, can someone please help me out with this?

    Thanks.

    Here are the results. I'm removing/masking some things that I think are not necessary/security to keep it short. Let me know if you need those as well. It's Wireless LAN adapter Wi-Fi 2 BTW.

    You keep the correct ip etc when its not working so it suggests the fault is the gateway when it stop from a cmd prompt try

    Ping 192.168.178.1

    See if its dead

    Find out what the Signal Quality is for the signal. This points towards a bad wifi connection not a Windows problems. You can use a program like this to find out how bad things are instead of having to repeat through tools in Windows that do not give a live report. Helge Keck

    I get Host unreachable and request time out.

    Also, in some of my retries via Windows troubleshooter I get There's something wrong with your network's proxy settings and the other about DNS is not reachable or something but then it's always default gateway error. I couldn't replicate those messages.

    You need to show the output from netsh wlan show all.

    If it's saying about a proxy check browser isn't set to use a proxy are you running anti virus they often run everything via a local proxy and malware can setup a proxy so do a full virus scanner

    Here are the screens from repeater and WinFi:

    The repeater is no more than 5-7 meters away from the PC. Another thing when internet doesn't work I can't even access the repeater interface either and sometimes the internet speed is extremely crap. Although mobile and mac works perfectly.

    Pretty overutilized is why you are most likely getting kicked off. Also -51dbm can place you at the edge limit of range for a 2.4ghz network if it is not properly setup. Depending on construction of the building, how many people have microwave ovens, etc that work in the 2.4ghz frequency range, the fact that there are nothing but 2.4ghz Access Points, you are going to see issues.
