direct connection to Modem I get 130Mbps

I have a fairly newer router Linksys EA6900 , the router gives me ~20mbps . and the weird thing once I configure my router and I unplug the cable and do a direct connect from the modem I get same router speed ~20mbps down from 130mbps

I tried another router , and that one also kills the speed to 20-30 Mbps.

What is the problem ? is the area where the router is killing the signal ?

why my router make the direct modem speed 20mbps after I plug it to the router and plug it back directly to my laptop ? can the router change the speed of the modem >? I am confused.

please help with any suggestions .

QoS/Optimizer software? something like cFosSpeed, try reCalibration

Hook computer directly to modem, power cycle modem. Run an automatic test here: http://testmy.net/auto so you can test speed throughout the day.

Then test with wired ports on router instead of wifi. The throughput of a lot of routers is limited.

The fact that you keep the same speed (assuming speeds are consistent) after the router is removed from the picture does suggest it's some kind of negotiation issue, but I can't say I've ever heard of something like it.

Have you tried cloning your PC's MAC address on the router's wan port?

Just to check, you are using a wired connection from the router, not any sort of wifi?

It would make your router look the same as your PC to the modem, in case the modem is purposefully giving the router a slower connection.

It's a long shot though. You should recheck wired performance through the router first. Also make sure you're using the same cable, in case that's a problem.

That really shouldn't happen. Either the router/wifi is a bottleneck or your speeds from the modem vary a lot.

Your WiFi Router has almost over 900 Mbps routing performance, so it shouldn't be the router. Test with a cable and if that fixes it start doing basic WiFi interference setup and site survey.

Try everything wired. Let's take Wireless out of the equation.

What are you using for a "Speed Test" site?
Does your ISP do burst or Turbo where speeds increase for a short period of time?
Have you tried different times of the day? I know peak for most is from about 5-9pm weekdays.

Yes this, Definitely do a wireless site survey and make sure things are not super congested, Also worth trying a different cable. I have seen this matter before.

I would also add make sure the router has current firmware, and reboot everything between tests just to be safe.
