To make sure it's not a hardware problem, you could boot with a Live USB
with Trisquel 7.0 (it has an older stable kernel) and see if you have
stable WiFi. If not, maybe this is a good opportunity to upgrade to the
best WiFi card compatible with fully free systems: Tehnoetic N450DB
(a/b/g/n compliant, up to 450Mbps, Dual Band, 3-antenna connectors):
