Confused. Huge speed discrepancy between router and modem connections

[Scruffy90]

Today I encountered a very perculiar issue. I was trying to see why my ISP wasn't providing me anywhere near the speed that they "offered" me and noticed that if I connected directly to the modem via my desktop, I got a little less than half of the speed I was getting from my router.

 

Router being used is the linksys e4200 v1 and I need to dig up the modem number.

My computer is using the onboard ethernet port on my mobo.

 

Any ideas as to why this may be happening?

Your modem is unable to provide the speeds?

Well the speeds offered to me by the ISP was 200mbps. When I hook up directly to the modem, all speed test reported ~ 45mbps. When I connect to the router, the speed test reports 91mbps. Shouldn't it normally be the other way around? Also, the ISP can't seem to figure out why I'm achieving only half of the theoretical speeds they offered me.

That's... wrong...  :wacko: Good job, you broke physics.

Can you ask your ISP to replace your modem? Especially if it's old. Never know what that can do to help.

They came buy yesterday. They were baffled by it too. Couldn't figure it out and they don't see it  as a big enough issue to pursue it, I guess i'm stuck for the time being. lol

I would suggest getting some opinions from HTML-based speed tests (no flash or other plugins). I usually use speedof.me and testmy.net for the HTML-based tests.

 

If I remember correctly, the E4200 firmware has QoS support, so if you have that enabled, please turn it off for the duration of the test.

 

As for the direct vs router difference, in my experience, Windows Firewall interferes with transfer speeds. Since you are connecting your computer directly to the Internet for your tests, I would not recommend turning it off. I mentioned it as a possible explanation as to why you are getting that difference.

I gave testmy.net a whirl and got a considerably lower speed with QoS off than I did with it on. Downloads were ~35mbps with it on and ~23mbps with it off.

do you have your line split in a weird way (for tv or through a UPS)?

Wow. That's weird. I normally get faster speeds with QoS off. Perhaps it is a different implementation from what I am using.

It's a possibility. I'm not to familiar with how a lot of the router tech works. My house is a weird computing conundrum lol
