    I just installed, obligatory "this OS is awesome, I am absolutely in love!"

    The only problem I am having is with the wifi. I maintain connectivity, however after only a few minutes of being connected I can no longer access hosts on my local network. I cant even connect to my router IP. I am attempting to connect via IP, theyre all on the same subnet.

    If I disconnect from wifi and reconnect, I am able to access them again but only for a few moments. I can access the outside internet without issue when this happens.

    Anyone know how to troubleshoot? Thanks for any help.

    Could you share a bit more information?

    Firstly what wifi card are you using and lets check that we're using the correct driver?

    run the command lsusb in linux, this will show your hardware devices and the hardware codes associated with them.
    Code (Text):
    This will give an output similar to that below

    Code (Text):
    Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
    Bus 001 Device 008: ID 1122:4455
    Bus 001 Device 006: ID 0bda:b720 Realtek Semiconductor Corp.
    Bus 001 Device 004: ID 0bda:0129 Realtek Semiconductor Corp. RTS5129 Card Reader Controller
    Bus 001 Device 003: ID 0b05:184c ASUSTek Computer, Inc.
    Bus 001 Device 009: ID 05e3:0751 Genesys Logic, Inc.
    Bus 001 Device 007: ID 413c:301b Dell Computer Corp.
    Bus 001 Device 005: ID 1c4f:0002 SiGma Micro Keyboard TRACER Gamma Ivory
    Bus 001 Device 002: ID 214b:7250
    Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
    In my case the 3rd item in the list is my wifi card (Realtek Semiconductor Corp.).

    Take note of the hardware id: 0bda:b720
    Then use this site to look it up: https://linux-hardware.org/index.php?view=search

    Type in: 0bda in the Vendor_ID field and b720 in the Device_ID field and click search.


    Click on the results link, this should give you additional data on what's the best driver to use.

    If you're already using the correct driver, please do post back here as it could also be a routing issue.
