I just installed Fedora 20 on a computer which previously had windows 7 on it (and Fedora 17 -- dual systems). It has a Bolse wifi adapter plugged into a USB port, and windows liked it just fine. However, Fedora 20 seems to have a problem with it, losing connection to the internet frequently. Network Connectivity shows that there is a strong wifi signal and that the computer is connected to the wifi system. But cannot ping with it whenever it loses connectivity.

Anyone have any thoughts on this??

I can only share the following report with you (refer to post by user 'l0b0' answered Oct 16 '13 at 19:56)

Interestingly, that user reported a little more stability was obtained using NetworkManager. You didn't say how your device is controlled. If you are using NM, try observing
while connected. Maybe it will capture the disconnection events and provide more clarity - even if it only helps with a bug report.

FWIW, I have read of similar accounts with users using 802.11n wireless connectivity with particular hardware that have had to disable 802.11n (router end), and drop back to 802.11b/g . 'Wireless N' is particularly susceptible to interference from nearby wireless networks etc. It may take a while for the Linux drivers concerned to mature a little.

That's about all I can offer.

Thanks. I am indeed using Network Manager. For right now I am just going to hardwire it with a CAT5 cable to the router, which works just fine, while I continue to research the wireless problem. I did see a comment somewhere where someone mentioned that the Bolse adapter with Linux seems to have a problem if the system goes to sleep. Seems (from that comment) that the Bolse does not wake up! If stopping and restarting Network Manager makes it work then that may be a clue. Anyway, should be fun to play around with it. Good article that you pointed me to, by the way.

Just a further data point. The internet connection goes away even when the system is being actively used, so the "sleep" issue does not come into it.

Stopping and restarting NetworkManager will make the internet connection pick up again. The wifi connection is there the whole time, but no internet connectivity (ping nytimes.com does not connect).

No "NetworkManager" file in the /var/log/ directory by the way.

For Fedora, I believe this will report NM messages

Not to be pedantic, but it is the connection that IS breaking. What you meant is that the access point is still available to reconnect with. (802.11 connectivity is not as simple under the hood as it first appears to be for regular users.) If I were you, the first thing I'd do is turn off 802.11n in the router, and then check the link stability again.
