Pi2 WiFi with USB Powered Hub

[Junos76]

Hi,

I have Raspberry Pi2 with the EDUP 300Mb WiFi adaptor: http://www.amazon.co.uk/gp/product/B00S ... ge_o02_s00

I've read that using a seperate USB powered hub can increase the throughput of the adaptor. Does anyone have any real world examples of how this has improved their WiFi performance?

Also, could anyone recommend a good USB powered hub that I can use to correctly power the Pi2 and also to power the WiFi dongle to increase its throughput? Ideally something small with a few ports would be all that's needed.

I'm currently using a recommended power supply, but if I can improve WiFi performance I'd ditch that for a powered hub.

Thanks

Many WiFi Dongles can require quite a lot of power therefore just increase the USB Bus from 600ma to 1200ma, add following to config.txt:

Code: Select all

max_usb_current=1

The RPi2B like all RPi's has only one USB Bus, therefore adding a Hub will do nowt for I/O.


This is a good comparision of Ethernet vs Wireless N speeds

I added that to the config.txt file and it looks like it has damaged my power supply as it's no longer working.

The power supply I'm using is the following, which was recommended on Amazon:

Is there a better or more suitable power supply that you could recommend that would be able to cope with this?

The RPF Official PSU

Increasing the ma with a decent quality 5V2A PSU should not cause issues

Good stuff. I'll order that power supply asap.

Thanks for all your help.
