Full wifi signal, but periodically no internet access

I have a strange wifi issue.

I have an almost brand new MacBook Pro. It's always connected to my home wifi with full signal strength. Even so, once in a while it has no internet access. Nothing which requires internet access works. The wifi is still connected, but the internet connection disappears. After a few minutes the internet access is back. This happens on and off constantly. If i restart my computer, the internet access immediately returns.

No other devices in my home have any similar problems which means it hardly has anything to do with the router.

Any ideas?

MacBook Pro with Retina display, OS X Yosemite (10.10.5)

Linksys DIR-855.

Firmware is quite old (from 2008). I have no idea how to update it though.

Hold down the Option key and click on the Wi-Fi Icon on the menuBar:

what do you get for PHY Mode?

Channel?

RSSI/signal strength?

transmit rate?

and very important, how many other Networks do you see?

There's no admin password required to log into the setup-page in a browser, if that's what you mean.

Looks pretty good. You are using the much wider 5GHz band, you have a good (signal-noise) of -25, and are transmitting briskly at 78Mb/sec.

The number of competing networks is a little scary. Let's hope most of them are using 2.4GHZ band. You should check that your Router channel is set to "automatic". This assures that when your Router powers up, it "sniffs" the frequencies and chooses the least crowded that gives it the best signal. That is why so many debugging procedures suggest, "reset your Router" as one of the early steps.

Bump.

This is starting to drive me nuts. Signal strength is always perfect, but the internet access still goes on and off all the time... no other devices (including another (older) MacBook Pro) have any similar problems.

No one out there with a magical solution?
