1 out of 5 eggsDon't bother

This review is from: ZyXEL BRG35503 DOCSIS 3.0 Residential Cable Modem Up To 160 Mbps Down and 120 Mbps Up RJ-45, Gigabit Ethernet DOCSIS 3.0, 2.0 and 1.1, Euro-DOCSIS 3.0

Pros: Worked for 6 mos

Cons: Worked for ONLY 6 mos.

Other Thoughts: Cheap. It worked fine with Comcast but died 6 mos in. Three attempts with Comcast tech support, including a home visit, were unsuccessful. Comcast's assessment was that the modem failed. Other troubleshooting sequences were unsuccessful. Unable to ip in after failure. As others have indicated: its junk, don't bother

4 out of 5 eggs1.5 years and counting ...

This review is from: ZyXEL BRG35503 DOCSIS 3.0 Residential Cable Modem Up To 160 Mbps Down and 120 Mbps Up RJ-45, Gigabit Ethernet DOCSIS 3.0, 2.0 and 1.1, Euro-DOCSIS 3.0

Pros: It's run on two different Comcast regions without issues for 1.5 years. In its new region, it pulls 100 mbps without issues!

As a Hitron modem, it's reliability is consistent with my previous Hitron modem DCM-202. That modem worked flawlessly since 2004 and was still working when this modem replaced it in 2013!

Cons: It doesn't come with the stand that the DCM-202 and Zoom 5341 come with. This costs it an egg since I would suspect that the stand helps keep the device cooler and saves valuable desk space.

Other Thoughts: I recently moved and Comcast at my new location was unfamiliar with this modem. I had to refer the technician to Comcast's supported model page:

http://mydeviceinfo.comcast.net/

This modem is clearly listed on that website.

If you're in a similar situation, refer to the above site.

Anyway, the modem works perfectly at its new location!

If you had a DCM-202, use its stand to help keep this modem cooler. It does get a little warm.

This an update of my first review:

5 out of 5 eggsDocsis 3 for docsis 1 price

This review is from: ZyXEL BRG35503 DOCSIS 3.0 Residential Cable Modem Up To 160 Mbps Down and 120 Mbps Up RJ-45, Gigabit Ethernet DOCSIS 3.0, 2.0 and 1.1, Euro-DOCSIS 3.0

Pros: Price, Manufacturer history,Quick ship

Cons: Runs hot

Other Thoughts: Won't deduct for running hot as simply tilt to one side of end standing up--attached cables support that posture. As other reviews state, the install difficulty is with Comcast, not product. After clarifying MAC letter for letter following morning, found that prior day Comcast tech fat fingered a digit.
