Wireless vs wired speeds, what's normal?

How much slower should a wireless connection be than wired assuming no interference and excellent signal? Half? 80%?

I just got a 75 mbps connection with boost up to 105. I hooked up my wireless router, it's a tp link 300N, link here. http://www.amazon.com/TP-LINK-TL-WR841N-Wireless-Router-300Mbps/dp/B001FWYGJS

It's a pretty cheap one I know, but reviewers said it is fast and reliable. One video review showed it getting over 75 mbps over wireless. When connecting via ethernet to the router my speed tests at speedtest.net are consistently in the 85 mbps range.

I have tried wireless tests on a laptop with built in wifi, my iphone 5s and my pc which uses a usb wireless N adapter. They are all significantly less fast, all around the same speed so I don't think there's any device specific issues. I'm in the same room, have complete line of sight to the router and it's only 5 feet away from my devices. I don't have any devices I can think of running interference, no baby monitors, I turned off my wireless controllers and bluetooth devices. Of course there are other wireless router's in neighbor's houses. On some channels I was only getting 5 mbps, but I finally found one that seems the best. It is averaging 25 mbps. I was downloading a game on steam and at one point it peaked at 50 mbps for a couple minutes but it could not sustain that and dropped back down to 25-30.

Is this basically the best it's gonna get or should I get a different router? When I couldn't get it to do more than 5 I called tp-link and they said it was broken and I should return it so newegg is actually sending me a new one. I'm just wondering if it will perform better. The N band should be able to get up top 300 mbps, far more than my hard line does, so I thought I'd be getting 50+ easily over wireless. I just don't know what to expect. At my old house I had a 25 mbps line and would average 18 mbps on downloads so I figured that was pretty normal, but this speed seems far too low compared to the wired, coming in at a third or less.
 
I think the one you got has some defect (it cannot sustain the operational speed) but it also can be driver issue. What Windows do you have? Some routers need a firmware update to Work well with Windows 8.1 (I don't know about 10).

A 300N router could have a MAXIMUM throughput of 150Mbps if you have a dual stream client. If you only have a single stream client then your max will be 75Mbps. You can check the link rate in the Windows task manager. If your link rate is above 150 then you have a dual stream adapter. If it is 150 or below you have a single stream.

To get best performance, you must have your wireless configured with WPA2 and AES encryption.

Your speeds will depend on the other end also.

What do speedtest.net speeds show?

Speedtest.net shows 20-30 mbps consistently once I settled on a good channel. I'll have to check the link rate later, I'm not by my pc, but tp-link support had me right click the connection from networking in control panel and show status and it said it was 200 mbps connection (I don't know exactly what this means or if it's the same as task manager link speed).

I'm still using windows 7, so I don't think firmware's issue, plus tp-link support verified it's on latest firmware. I'll check the encryption, I think it's doing wpa-psk and wpa2-psk. I dunno what differences in the types of encryption are, but I'll look for AES setting and try it.

You say maximum throughput of 150mbps but the router clearly advertising 300 mbps on this model. Not that my line speed is close to that anyway.

It could just be a bad piece of hardware, I'm getting a second one of same model this week so I guess we'll find out! But I want to know what to expect, if everything is setup right and my line speed is 75-100, should I get 50-75 mbps on wireless?

well I give up, can't figure it out.

The new router came in the mail. Same model and everything, they just sent a new one cus speeds were slow. I flashed the latest firmware to my usb wifi adapter as well as the latest firmware off the web for the router. No luck. Actually worse than the other one. So I found openwrt firmware for it. Then I kicked off every device, my wireless printer, my wife's iphone 5c that's a billion updates behind cus she has too many photos on it, the whole deal. Speeds still stabilizing around 30 mbps. Can't do better. I also for some reason cannot select N mode only, only mixed mode.

I'm just really shocked this router can't do more than this. For example I got the openwrt firmware link from this thread. https://forums.techguy.org/threads/solved-tp-link-router-fast-wired-slow-wifi.1133322/

This guy was able to get 50+. Other reviews of this device have shown it to be blazing fast but I just cannot get there using all channels, removing all my devices, interference etc.

Any other tricks to try?
