New Equipment versus Old Cables

Thank you for your reply. My plan was supposedly automatically upgraded and shows 500Mbps as the currently available speed. Xfinity wants me to upgrade my equipment. As previously stated, my current modem (Motorola MB7220) is rated up to 343 Mbps but can only reach up to 184 Mbps on a wired PC.  It is no longer on the list of approved modems. The rounter has Gigabit Ethernet ports. Once again, the question is will I realize an improvement in speed with upgraded equipment considering that my house cabling was installed in 2003. If the cable is a bottleneck, then I any equipment upgrades would probably not be worth the cost. Cable markings are as follows: 2003 2000896 CM c(ETL)us OR CATV (ETL)us 18 AWG.

Thank you again.

You're welcome, user_0zx38i! I understand your hesitation with upgrading the modem until you know if that would help or not. A technician would best answer that for you. We would be happy to work with you on any charges to send a rental modem so you can test the speed. That would tell you if it would be worth upgrading your own modem or not without needing a visit. 

Please send us a direct message with your full name and complete service address to “Xfinity Support”. To do so, click on the direct messaging icon located at the top right of this forums page.

Here's the detailed steps to direct message us:
• Click "Sign In" if necessary
• Click the "Direct Message” icon (upper right corner of this page)
• Click the "New message" (pencil and paper) icon
• Type "Xfinity Support" in the to line and select "Xfinity Support" from the drop-down list
• Type your message in the text area near the bottom of the window
• Press Enter to send your message

Thanks for the response. However,  I am not keen on the concept of renting Xfinity equipment to verify speed that Xfinity says I am getting. I now think the best approach is to ask Xfinity to verifythe speed delivered to this location since my previously approved equipment has never come close to its rated speed. In fact, I previously resorted to downgrading the tier of service I was paying for since the service speed far exceeded the modem's rated speed which was unattainable.

Would a Direct Message be the best way to accomplish this?

Thanks again.

user_0zx38i To be fully transparent, direct message would be the only way to handle this. To confirm diagnostic specifics, and look over the history, we need to pull up your account and go over everything. When you own the equipment, our scope is pretty limited, on our end, and even our field teams side of things, the core of our support is to provide you with the proper coax signal speeds and a provisioned bootfile. Management of the owned equipment does fall on you, and manufacturer to isolate speed issues. We can reprovision the device, and view our inbound coax signal flow which gives us a clear picture of how the signal is running. The core of our new promotions actually include the cost of our xFi gateway/unlimited data right into the package which is very popular. When you are using our equipment, we need to support that entire signal path/performance. We would love the opportunity to dig deeper on this, your satisfaction and confidence is always our top priority. 

Thank you for your response. 

Good information. Thanks

user_0zx38i You bet! 👍 It is always a pleasure to help a valued member of the Xfinity family. Reach out to us DM if you want to explore some of those options.

I think so. (But it's not easy to just google an answer!)

I can find posts mentioning RG-6 quad shield on AVS forum in 1999.  And 1999 is when that forum was created so I can't search earlier.

As I recall, in the 80s, my local cable company put the local channels on "off-by-one" channel assignments.  Sometime around 1990 they put them on the same channel as broadcast.  I had a nest of cables, VCRs, splitters, and got a bunch of multipath when they did that.  I complained and they sent a tech who said: oh that's your lousy store-bought cables.  And then he proceeded to cut a bunch of "good stuff" to length for me.  I'm pretty sure the "good stuff" was RG-6 quad shield. In any case, he was correct - the ghosting went away when he replaced the cables.
