re: Huge difference in wired and wireless speeds?

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

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.
Wireless n is capable of achieving speeds of up to 450 Mbps but only when using three antennas and doubling the channel width to 40 MHz. Typical laptops only operate on the 2.4 GHz band which limits bandwidth to 20 MHz and they have only a single antenna. Max speed in this case is 72 Mbps, not much more than 802.11g.
A dual band system also operates on the 5 GHz band which allows you to increase channel width to 40 MHz. Each antenna supports speeds up to 150 Mbps so with three antennas you can reach 450 Mbps.
Remember that both your router and the network adapters on all of your devices have to have matching capabilities. A typical high-end 802.11n router will run you about a hundred bucks and an external USB three-antenna dual-band wireless adapter around fifty bucks.
The emerging standard is 802.11ac which offers substantially higher speeds but at this time is very pricey, more than double the cost of the 802.11n setup. Also, from the reviews I've read, only a handful of them really deliver the speed. The rest were very poor performers with some not even achieving 802.11n speeds.

I looked up specs and saw my Memory: 8GB, Wireless Controller: Intel Centrino Wireless-N 1030, Speed: 1333 MHz / PC3-10600. So mine is only 1.33 MHz?

I understand what the router is for, but what is this wireless adapter for? Goes on/in your laptop or somewhere else?
TIA

It replaces the one built into your laptop. It plugs into a USB port. THIS is the one I use to get the full 450 Mbps.
Note that these adapters typically bill themselves as N900 devices but their max speed is 450 Mbps per band for a total of 900 for both bands combined.

The Intel Centrino 1030 is your internal wi-fi card. It's a single band card operating in the 2.4 GHz band. While Intel claims up to 300 Mbps receive speed, I doubt that you would ever come close to that because it's predicated on using two channels (40MHz) in a band that only has 11 channels allocated and even at 20 MHz there are only 3 non-overlapping channels. It's also predicated on your laptop having two built-in antennas, which most don't.
BTW, that card is also what provides Bluetooth support for your laptop. If you add an external wi-fi adapter you will have to disable the internal card and will probably lose your Bluetooth.

Ok, thanks. So this raises what my laptop can do by plugging into USB.

I actually use my Bluetooth quite often on my mobile printer, so that may not work.

Yeah, I live in Waikiki so that could be part of it, but I never go above 15mb down wireless. I can get maybe 20mb wired. Part of that is the cap from Time Warner. I need to pay for faster speeds. But likely, I don't have the 2 antennas you're talking about.
I'll probably buy a new computer at some point in the next year or so. I just got this one a little over 2 years ago and it already annoys me with it being slow to process, slow to boot (I know, get ssd), and now knowing I should be looking for more built-in antennas. Thanks again

If you're running an internet speed test it's going to top out at the maximum speed of your broadband connection, not your internal wi-fi network. If you want to see your wi-fi speed, right click on the connection and click status.
Re the Bluetooth, go to Device Manager and find the network card. If the Bluetooth is listed as a separate device you probably can disable only the network portion of the card and keep Bluetooth operational.

It went from 19 to 26 up to 39 for a second. Just went to 49mbps. Seems like 26 is the one it sits on the longest.

There's a list for Bluetooth Radios and there's 3 items: printing support, Intel Bluetooth 3.0 + high-speed adapter, and Microsoft Bluetooth Enumerator.

If you also have a wireless network card listed, see if you can disable that without also disabling any of the Bluetooth devices.

If you're close to the router and have a good, strong signal, try changing the channel on the router. It's probably set on 6 as the default; change it to 1 or 11.

It was on Ch 8, but I just switched it to 11. I also changed it from 20mhz only to auto 20 or 40. I'm now getting 72-104mbps
Hopefully this keeps working, but I think it will slow down as more people get home and get on.

If you live where there are other networks within range there can be interference if they're all on the same channel. That's the beauty of the 5.8 GHz band--much less congestion because fewer people use dual band.

Yeah, I'm in the heart of Waikiki. Lots of interference. I'll have to look into 5.8 for sure.

Download inSSIDer here: LINK. It's a useful free utility.
This will let you view the wireless network traffic around you. You want to put your router on the least congested channel, and do it on channel 1, 6 or 11. If you set it for any other channel, then you cross over into other channels, causing potential issues for you and others.
This works on both 2.4Ghz and 5Ghz networks, assuming your computer's network card works on 5Ghz networks.

Good product but it's no longer free from the Metageek source site. I'd think twice about downloading an executable from an unknown site.
