A couple days ago ping connect: no buffer space available though, my wireless connection started dying on me. I hadn't changed anything, so I'm not sure where this came from. The symptoms are always the same, it connects to the wifi just fine after boot, then dies 5-10 minutes into regular usage. Running a constant ping goes from regular responses to "sendmsg: No buffer space available" and then to "sendmsg: Network is unreachable". I found a few different threads about this and tried a few things, but no change. I'm using a Realtek USB adapter, but the driver version is much newer than one someone listed as problematic. I also tried setting my wireless router to g-mode only, same issue. I only recently made the switch from the "w" word to Ubuntu, so I'm not sure where else to look. Any ideas? wireless networking 14.04 share|improve this question asked Jun 28 '14 at 2:56 user298535 11 add a comment| 1 Answer 1 active oldest votes up vote 0 down vote I have this problem too.

It just happened to me in Win7 64bit. Chrome and Firefox stopped being able to connect to any web pages, windows file sharing stopped working, and WinSCP and PuTTY both gave errors that included the words No buffer space available. Oddly, Ubuntu 10 running under VirtualBox seemed to have no problem making new network connections - maybe it holds a number of network buffers in reserve. To find out what software is leaking network buffers, you need to close programs until the problem goes away. So I started closing programs and trying the WinSCP connection after each program I closed, but the error persisted. Once I'd closed every visible progr
