Hi Guys I found the problem.

It's actually the modem Linksys CM3024 which has a faulty intel chip, I switched back an old motorola modem, can get steady 110mbps out of it.

Thanks again!

Yep! Any model/brand of modem/router or all in one Gateway that runs off the cursed Intel Puma 6 chip as ones seen here: https://www.dslreports.com/forum/r31122204-SB6190-Puma6-TCP-UDP-Network-Latency-Issue-Discussion are automatically bad, will give you problems and should be gotten rid of ASAP. What motorola model did you switch to? Does it have a Broadcom chip in it? (Broadcom seems to make good chips 99% of the time. I've had several modems and routers over the years. All with Broadcom chips and no issues)

It's an really old SB6121, sorry i don't know what chip it use.

It only support up to 170mbps, but my service is only 100 so it's working great now.... I really forgot why i even bought this Linksys CM3024......

Good to hear it still works for you. I think that modem did run off a broadcom chip. It's still old, though. So you may want to think about upgrading. If you're in the US and are on Comcast, here's a few options for you. Having a modem that supports more than the 4x4 channels the 6121 will give you a more stable, consistent connection so you'll get your 100 no problem.

Netgear Cm600 if you want to go under 100, I think you'll be able to get 500+ from it. I think the limit is around 700, but 500 is much more attainable. https://www.amazon.com/dp/B06XGZBCKP/?tag=snbforums-20

Netgear CM1100, if you want to go all out, be done with it and sit on it for 5 years: https://www.amazon.com/dp/B07Q5VM51Y/?tag=snbforums-20 I use a earlier model of this modem, the 1000 and get 950/42 off it.

The ones I listed here are all broadcom chips and you'll be leaving the crap the Puma 6 chip gave you behind.

I hope that helps you in the future.

Thanks for the info!

However, comcast only offer 100MBPS at my home area. so further upgrade seems unnecessary at the moment.
