Wireless DNS-320L / Alt-F

[Ronaldo Antoni]

Essesgadgets of china are very cheap and I happen to have a wireless bgn usb leaning here. I decided to test it on Alt-F. 

In ubuntu it is detected by lsusb as follows: 

Bus 003 Device 005: ID 148f: 5370 Ralink Technology, Corp. RT5370 Wireless Adapter 

Alt-F, lsusb displays nothing. in / dev, it creates an entry called 1-1. 

Now the question: is it possible to do what I think or you better give up now?

Search the forum for usb and mdev.conf, there exists a solution for that.

give up, there are no wireless usb kernel modules in Alt-F

There is a possibility in the not too distant future this work?

It's not a priority for me...

What I have though more than once is to use a wireless USB adapter as an Access Point, that would be interesting. But finding the right USB adapter is a kind of a lottery.

I have already done some preliminary research on that:

http://wireless.kernel.org/en/users/Devices/USB

http://elinux.org/RPi_USB_Wi-Fi_Adapters

http://pplware.sapo.pt/linux/raspberry-pi/como-transformar-o-raspberry-pi-num-access-point-wireless/

 I just don't want keep buying USB adapters until one fits.

Of course if I accomplish this then your wireless request will also be fulfilled.

But, again, the only way for me to not forget this is to fill a ticket request.

According http://elinux.org/RPi_USB_Wi-Fi_Adapters, RT5370 (148f: 5370) works in AP mode. I am available to help with anything you need!

Thanks.

But the current kernel is not able to upload firmware to devices, and most if not all wireless chips needs that, so adding USB wireless support is currently not an option.

And after adding that capability to the kernel it is needed that its size does not grows significantly, or it will not fit the available flash memory kernel space in the DNS-323  (1.5 MB), which the base reference for all boards.

Thankful!

Does everything need to be included in kernel? Isnt it posible to make some things as kernel modules and load them later in the boot

Of course not. On the kernel only the always needed drivers are built in -- network, disk, ext2/3/4, raid... the kernel-modules package has the optional ones.

For some modules the kernel needs extra code to handle them, and some of it can't be modularized. Even if that extra built in support code is small it adds up and slowly the kernel gets bigger and bigger. On my desktop computer the compressed kernel image, not counting modules, has 5MB (the modules folder itself has 134MB).

The DNS-321/323 kernel can have a maximum of 1.5MB, that's what is available for it in the 8MB flash memory. The 320/302L/325 kernel can have 3.1MB

So, the kernel has to be compiled with all modules that will possibly be loaded and yet be smaller that 1.5MB -- this means that something has to be left out.

I would be great to have wireless usb support so that we could put the NAS anywhere in the house (I could find a cold place for it in the summer).
If all the card specific drivers are compiled into modules, the very basic wireless support still can not fit in the kernel space?

[Goolias Andreas]

You can connect to a wireless bridge AP to make this, while not as versatile as the USB dongle, at least it served the purpose of making the NAS portable so to speak.
For starters, TPLINK running on Openwrt can be configure to be a wifi bridge.

[Norbert Horváth]

Yes, you are right, I've tried it with a WRT54GL and it works (54Mbit only, but good enough for a test). But it would look great plugging a 802.11n stick into the USB and I only need a power socket. And I like experimenting, and I have a spare stick to experiment with... :)

[autosoccors...@gmail.com]

I think it is more easy to buy a repeater (€20) wireless (with ethernet port) and connect it to nas using cable.
A fast access to nas is only possible conecting it directly to router, it is not necessary to be wireless
