connect an rMBP to cable modem via USB?

[jk73]

As I just mentioned in a different thread, I'm staying at my sister's place for a few months and she has a non-Wi-Fi cable modem.

The modem has both ethernet and USB ports. My rMBP doesn't have an ethernet port, so that option is out (unless I buy the Thunderbolt-to-Ethernet adapter).

I tried connecting the modem directly to my rMBP via the USB port and it worked for about 2 minutes, but then the connection dropped. The same pattern repeated 3-4 times before I gave up.

I know ethernet is the standard means of connecting a cable modem. Does this sound like a compatibility problem with the rMBP and/or modem, or could it be an unstable internet connection? It seems odd that it works when first plugged in, but then dies out within 1-2 minutes afterward.

Thanks for all feedback.

if ur directly connected through USB, I recommend disabling WIFI just to be on the safe side.

Yes, I had Wi-Fi disabled, but the USB connection only worked for 1-2 minutes each time. From Googling, I'm getting conflicting reports of whether a Motorola SURFBoard modem is Mac-compatible.

buy a cheap router and solve your problems

Unfortunately, most USB connections are completely unreliable. I know the ISP I work for won't even support connecting via the USB because it's so unreliable. You can find a cheap router (under $40) that will work while you're staying at your sister's. I'd recommend that over using the USB connection.

If you are staying get her a refub Airport Extreme.

They can use the router connections on the back for their hardwired computer and you get WiFi.

And kick in for some food also.

The Ethernet adapter is $30. Spend another $10-$20 and get a good router for wifi.
