networking - Connection periodic failure after 14.04 upgrade - Ask Ubuntu


after upgrading morning, i'm finding connection drops every 15 minutes.

this has happened on multiple access points , other clients aren't experiencing periodic connection failures. nothing showing in syslog or dmesg.

lshw output: 

  *-network                   description: wireless interface    product: wireless 7265    vendor: intel corporation    physical id: 0    bus info: pci@0000:02:00.0    logical name: wlan0    version: 59    serial: 34:02:86:83:47:b7    width: 64 bits    clock: 33mhz    capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless    configuration: broadcast=yes driver=iwlwifi driverversion=3.19.0-31-generic firmware=25.17.12.0 ip=192.168.2.142 latency=0 link=yes multicast=yes wireless=ieee 802.11abgn    resources: irq:50 memory:f7000000-f7001fff

i don't disconnect message or when connection seemingly drops. , pinging 8.8.8.8 provides odd output:

ping 8.8.8.8 (8.8.8.8) 56(84) bytes of data. ping: sendmsg: no buffer space available ping: sendmsg: no buffer space available ping: sendmsg: no buffer space available ping: sendmsg: no buffer space available
