HP hs2350 WWAN modem loses connection ability after Windows 10 may 2020 / b2004 update. RRS feed

  • Question

  • Hello!

    After update to may 2020 compilation I can't use my HSPA+ modem.

    When trying to connect to cellular network, I'm getting error:

    Can't connect to this network.
    Cellular data isn't working properly. Try again later.

    Before may 2020 update, cellular was working perfectly. When booting to Ubuntu on the same machine, cellular connection works. I tested second modem (I had a spare), and it displays the same behavior.


    computer: HP Probook 6470b
    modem: Ericsson / HP hs2350 HSPA+ WWAN mini-PCIe modem (this modem is whitelisted in BIOS, cannot upgrade)
    firmware: R3C11 (this is upgraded firmware - this modem out of the box doesn't work with Windows 8.1/10)

    APN & other connection settings were verified, SIM card is seen, I can search for networks and see signal strength, yet not connect.

    At least one user has identical issue (Polish forum, post is in Polish language):

    He had the same findings, verified going back to 19H2 Win10 build fixed connection loss.

    This is probably the closest I can do to filing bug report - what should be my next steps?

  • Your current practice is correct, your HP hs2350 WWAN modem should have compatibility issue with the latest 2004 version, then lead to current connection error, roll back to previous version is a good method.

    You could wait for update from both of Microsoft and HP.

    The Microsoft community has a similar case and you could use the method in reply to check result.

  • Thank you for confirmation.

    The thread you mentioned refers to firmware issue, which I have already resolved - the device requires a firmware update to work with Windows 8.1 and Windows 10 at all, otherwise driver installation will fail.

    There is significant amount of threads on HP forums, but nothing about Win10/2004 issue.

    No rollback for me, full reinstallation :(

  • Well, hope you can find something in HP forum, wait some days and delay 2004 version's upgrade.

    Please mark the reply as an answer if you find it is helpful.
