Hi All,

 

• I have a 600mbps Internet only plan from Xfinity/Comcast.
• I purchased a Netgear C7000v2 Modem Router (AC1900) to replace my old router + modem setup.
• The New Netgear C7000v2 Modem Router is able to go past 600mbps over wired connection but it can't go past 270mbps over 5GHz wifi network. The Netgear is capable of 1.3gbps over 5GHz network.
• My old router (AC1900) + Arris Modem setup was able to deliver speeds upto 400mbps on 5GHz wifi network and full 600mbps over wired conection. If I connect the Old router to the New Netger Model router, the old Router is still able to give 350mbps+ speeds on 5GHz wifi Network.

 

I have tried the following troubleshoot methods already and none worked.

1. Factory Reset the Modem Router.

2. Changed 5GHz Channel to 161.

3. Changed CTS/RTS Threshold from 2345 to 2304.

4. Changed DNS Address to Primary DNS:8.8.8.8 & Secondary DNS: 8.8.4.4
5. Changed MTU size from 1500 to 1492.
6. Power cycled the modem router.
7. Observed the connection for 24 hours.

8. Firmware version is v1.03.03 (Latest). I asked Xfinity support to reflash the firmware (Since the firmware is provider managed) but they were not sure how to do it.

Questions

1. What are my options?
2. Am I eligible for a Brand New Replacment if this can't be fixed?
3. Did aybody else face similar problems and what was the fix?
