    Hi, I'm new on the forum. I hve some questions:

    -Desktop computers connected with Ethernet are not affected, right?
    - Laptop or Notebook connected with Wi Fi that have received Microsoft security update of October 10th are protected if the router doesn t received a firmware update?

    Thanks

    Hi and welcome. Yes.
    Yes in theory if the only other device on your network is that laptop then you should be safe. That is if no other bugs in the WiFi protocols are disclosed at some point in the future.

    I have also 3 smarthphones and a tablet but with them we don't do bank transaction or other important things, only whatsap, facebook and play so for these if there will be no update I have nothing to do.

    Thanks for the reply Krusty

    LEDE/OpenWrt (DD-WRT as well) patched this up already, within 24 hours of disclosure. Always great to see open source community working together efficiently. Although there is more to this than simply patching the access points, routers, etc. The client devices, as we know already, need the patches as well.

    So does both device and router need to be update/ patched? Or just router?

    You should patch client devices too.

    I need to call AT&T see if they're going to send out update patch for their modem router combo, does anybody know if they have one or use AT&T DSL?

    Also as noted in the technical articles on this vulnerability, the attacker must be in Wi-Fi router range to pull off the attacker. So if you're a home user and your next door neighbor is a hacker, I guess you should then be worried. Or the attacker outfitted his cat for WAR driving; see my separate posting on that one.:D

    Not to mention, that SSL traffic in unaffected, so not much has changed, http traffic should never be considered safe, it can be easily eavesdropped anywhere on the route.
