Just upgraded my crappy rented modem/router with a Netgear Nighthawk AC1900 model c7000 today hoping to increase wifi speeds but that was not the case. I used to only max out at around 180mbps on ethernet and 70 on wifi on the rented router and after the upgrade I'm at over 300mbps on ethernet but still 60-70 on wifi. The laptop is a Acre Aspire E1-737 running windows 7 home premuim and has a Qualcomm Atheros AR956x Wireless Network Adaptor. Any help or advice would be appreciated, thanks for your time

That adapter is a 2.4Ghz only adapter. It is single stream from what I can determine which means the link speed will be limited to 150Mbit and your throughput will be about 1/2 that. If you are getting 60-70 Mbit throughput then that "is all she wrote" ... Most of the capabilities of your Nighthawk are wasted because your laptop is limited.

What wirelesss band is your computer connecting on? Some bands only support 60Mbs... Make sure it is connecting at ac speeds, and it should go WAYYYYYY up!

I also found this on the Microsoft site:

In short, AR956x hase single channel capability. That means WLAN card can connect to router at 20MHz bandwidth only on speed of 72,2Mbts. If you can switch bandwidth to 40MHz the connection speed will 150Mbts. I've changed Atheros AR956x on my Toshiba L50-A on Intel 6235 (no tweaks or tricks were needed). This WLAN card is dual-channel, supports 2.4GHz and 5GHz networks and on bandwidth of 40MHz connects to my router at 300Mbts speed.

Looks like you need to find set cards settingas and switch to 40Mhz setting instead of 20Mhz.

40Mhz is "un-neighborly" if you live in a WIFI congested area. You are interfering with adjacent clear channels. I don't recommend it unless you have no WIFI nearby. Your better solution is to get a dual band USB adapter.

What they said above. Collision avoidance(packets get sent back to confirm and ensure the properly made it. This is something that is not required with wired connections because they have other ways to deal with collisions[and with modern switches instead of old hubs(boy did the collisions fly of those things), I do not think they happen very much, but do not quote me on it]) on wireless wastes a good around 50% of the theoretical speed. Marketing won out when they called these speeds(or at least have for most). Always cut them in half at least.

There are too many variables to WIFI. You could try different channels on your router (1, 6, 11). You might have moved or rotated your laptop. There is no surefire way to maximize WIFI.

Ahh I see. Any recommendations on a dual band USB adapter? and would that take full advantage of the 300mbps minus the interference ect.. thanks for all the help
I actually have a netgear wireless N-300 usb adapter from a long time ago, but dont think that will do the trick

If you are getting 110. I think you are doing pretty well. Some cards may support using multiple channels to get more speed, but all parts require that feature to work.

Something as simple as a microwave can disrupt 2.4 ghz networks(as can some other things). For a good laugh, I am sitting on a 20 megabit(supposed to be getting upgrades to 50 when they are done upgrading the service) download service. any wireless has me covered.

You're actually probably better off upgrading the wifi card. It's not that hard, and will use the two large antennas built into your laptop. The USB adapters don't have antennas, and their range is severely limited as a result. Realistically you can expect a max of about 110-130 Mbps at 2.4 GHz. 5 GHz can easily hit 250-350 Mbps, with higher speeds being possible but dependent on config and range/interference.

If your model looks like the E1-731, it's the small item above the two memory slots in this video. The guy unplugs the two antenna leads at 2:50-3:00.

The cards are about $20-$30 and install like a memory module, plus one screw (and you have to plug in the antenna leads). You should be able to download drivers from the manufacturer's website. The interface is mini-PCIe, so to the laptop it looks just like a PCIe card plugged into a desktop. (You can actually buy a cable and box which lets you plug in a desktop GPU into a laptop via the interface.)
