My laptop has a Intel 5300 wifi card. It works, but I find that the connection can be a little patchy. Sometimes whilst browsing the web the browser kind of sits there waiting for a while and then all of a sudden begins to load pages. I don't experience this issue using Windows on the same laptop, or using a wired connection in Mint (Cinnamon 14 32bit, by the way) so I suspect the wireless card. The laptop is around 6ft away from the wireless router. Signal strength is around 100%. I see from iwconfig that the number of excessive retries increments constantly whilst the wireless network is active. Any ideas where I should start when troubleshooting this?
Here is the result from mintwifi. When this was taken I was connected to a router that is quite far away, the signal is weaker.

Rather than invoking init scripts through /etc/init.d, use the service(8)
utility, e.g. service smbd reload
Since the script you are attempting to invoke has been converted to an
Upstart job, you may also use the reload(8) utility, e.g. reload smbd
