Huge difference in wired and wireless speeds?

I've looked everywhere and can't really find an answer to this. We have Comcast's highest speeds offered in our area at 105 MB/S. Our wired speeds are consistently in the 105-115 range, but our wireless caps out at 30-35. At first, we used the built in wireless on the Comcast Gateway, then we switched to a Linksys E1200 we had lying around. Neither gave us over 30 down through wireless.

Do I just need to look into a beefier router or is there something I'm missing settings wise that might fix this?

Wifi sucks compared to wired.

There are probably environmental factors in your house that are causing the issue.

It really shouldn't matter though. It's not like you are actually going to see a 30mb download speed on any normal practical usage.

Are we going to do this in two different threads...?

I assume your router and/or wireless devices are 802.11g, which has a theoretical max of 54mbps. Real world speeds won't be that fast, and 30-35mbps sounds pretty typical. You can try different channels to maybe eek a little more speed out of it, but it won't be much.

You have two options:

#1 Wire everything that you want to be faster

OR

#2 Get a router that supports 802.11n or 802.11ac, AND upgrade the wireless devices that you want to be faster to match.




#1 is better and cheaper, but obviously not always ideal or possible. #2 can get pricey, and is likewise not always possible. Maybe give us more detail as to what you are trying to accomplish or what problems you're having, and also what type of devices you're using.

My router is a wireless N and my laptop has a wireless N card. Both should support up to 300 mb/s wirelessly. That's what's confusing me.

Also, what were the chances that someone had already asked your question on a board that is barely an hour old?

Pretty fricking good!

As already mentioned, the top speeds listed are theoretical. If you get more than half that speed under perfect conditions, you're doing pretty good.

Does the device have line-of-sight to the router? If not, you can cut that speed in half again.

Is the device within 25 feet? If not, you can cut the speed in half yet again, and cut it in half for each additional 20-25 feet.



These are all rough estimates, but should give you an idea of what to expect. If that wireless-n device is in a different room and more than 25 feet away from the router, I wouldn't expect anything over what you're getting (30-35mbps range).

I can be a foot away from it and I still max out at 30.

There is also such a thing as being too close.

Check the connection details to see what speed was negotiated.

There may be a lot of interference: cordless phones, baby monitors, the neighbor's wifi, etc. Have you tried different channels?

I don't believe so..I mean, I got 30 using two different routers: the Comcast modem/router combo and the Linksys.

How would I check that though?

Yeah I've tried different channels. I've done most of the "common fixes" for slow wifi speeds to no avail.

Check the mode set in the router..You'll know right away if it is only set to B/G or N
