    Exclamation Wireless cycling between connected and disconnected

    My friend has a Acer Aspire 5733Z-4851 it keeps disconnecting and connecting to his wifi but his hard wire will run just fine. Any suggestions?

    Re: Wireless cycling between connected and disconnected

    I really hate it when the inexpensive modems place both wireless and wired connections on the same subnet as it makes it difficult for a laptop to communicate unless good metrics are set. End rant, sorry.

    Suggest changing your default route for the wlan0 interface to an IP address instead of the "www" currently being used. A geek would do this via the route command (run "man route" in a terminal window for the syntax). It can also be set via "Network Connections" using the graphical interface. You'll need to know the IP of the modem (192.168.0.1 is common for most vendors using this subnet).

    Ok so can you please tell me more "detail" on how to do this please, I see the route button under the "Network Connections" and what do you mean the ip of the modem? the submask net for it?
