May I know if you are getting gigabit speed? if so, what type of laptop/pc are you using?
Because I don't think there's anything wrong with my modem/cables at all, since the tech used his device to test my cat5e cable and was getting 950+ mbps. However, my computer is unable to get up to that speed. It is a gaming laptop that has a Gigabit NIC.
So I'm realling wondering what type of computer are you using?

So I upgraded to the Gigabit internet. I have the 3.1 docsis Netgear modem/router C7800 (the best one from netgear right now AND also listed on the xfinity website as approved equipment). I'm using Cat5e and Cat6 ethernet cable to connect to my laptops. My two gaming laptops also have Gigabit NIC(Network Interface Card). The bootfile was also updated correctly to the C7800.
I believe I have all the requirements to handle gigabit speed.
However, I can only get up to around 500 mbps wired. I know that it's supposed to be in the 950 mbps range. Here's a video of someone with the EXACT modem and EXACT gigabit internet service from comcast. https://www.youtube.com/watch?v=41cTLHdrv8U He litterally just plug in the modem and is able to get to 980 mbps speed.
I don't know what seem to be the problem with my laptops. I've already looked at various online forum for advanced configurations such as disable the router firewall, disable the jumbo frame/energy efficient ethernet/green ethernet and setting the "speed and duplex" to autonegotiate and 1gbps. Nothing works. There was a comcast technician that came and he tested the speed with his device and was able to get the gigabit speed on that device. However, he also doesn't know why my laptops aren't able to get up to the gigabit speed, even though all the equipments are gigabit-compatible.
I've tried to contact comcast over 20 times but nothing helps yet. Most are useless trouble shooting step like turn the modem off, and on again...reset my browser setting to default, clear the cache and cookies(really?).
Is there someone knowledgable about this topic that can help me?
