Wifi Capped At 40Mbps On A 300M Internet

thLullaby · Jul 9, 2015

Greetings,

This is my first time seeking assistance, do let me know if more information is required. I own a 300M internet connection but is somehow unable to hit anywhere near 300 Mbps with my built in wireless. However, I am able to hit close to 300 Mbps when using an external Wifi adapter. This have been giving me lots of issues for the past few days. Would be great if someone could assist me with the issue

Wireless Adapter: Realtek 8821AE Wireless LAN 802.11ac PCI-E NIC
Operating System: Windows 8.1

Are you using an ac modem?

Paul NZ :

I assume so, not certain how to check. My modem model is FG7003GRV(AC).

Could be a setting somewhere thats wrong. Looks like it is an AC modem. How far are you from it?

Sometimes it can be the driver you installed for the adapter. Did windows install it or did you download the driver from the site?

Paul NZ :

Both windows and Realtek gave me the same drivers. Note that I am able to utilize the full 300Mbps when connecting via an external wifi adapter (USB) from the same place. I also tried resetting my modem to no avail.

I have tested several top tier wireless routers and devices. Wireless connection usually gives you less maximum bandwidth than the available bandwidth that can easily be obtained from wired connection through Ethernet cables. If your wireless device is closer to the wireless router, it will improve the rate, but it will always be capped by the capacity of the wireless chip or adapter. Some wireless chips have physical and bandwidth limitations.

Must be a setting on your computer then thats wrong. If something else gets 300. Or that card is faulty

Umm I wouldn't say that this is 300 at the mo a N600 dual band USB adapter. I'm like between a wall and the modem (in the lounge) (I'm in the bedroom)

George Phillips :

Yes, but my concern is that the external Wifi adapter gives me an average of 280 Mbps whereas the build in Wifi adapter only gives me an average of 40 Mbps.

Paul NZ · Jul 9, 2015

So youre using 2 wireless adapters on the same PC? Probably not a good idea if you are. Ones probably hogging the other

Is the onboard ac as well?? Probably isnt

Paul NZ :

I only use one at any point of time, I simply used an external Wifi to test the speed against my internal Wifi.

So if the pci-e is ac whats the onboard wifi?? If it isnt AC or dual band it wont go as high as 300

Paul NZ :

This is the onboard wifi: Realtek 8821AE Wireless LAN 802.11ac PCI-E NIC

Paul NZ · Jul 9, 2015

Did you try the drivers on the mobo site if the wireless is built into the mobo?

Whats the mobo?

Paul NZ :

I only know it's Asrock, I don't think it is attached to the MOBO as someone did came to replace the Wifi part for me and it's a standalone part from the looks of it.
