and possibly add these too:
defaultroute
usepeerdns

to watch the log, uncomment the “debug” line and use the command
logread -f &
to do the equivalent of a tail -f /var/log/messages in linux. (Or just use logread on its own to see the most recent log messages)

I’ve run into USB problems sometimes that had to do with OHCI vs EHCI vs UHCI. Could you try unload the usb-ohci driver and load ‘uhci’ instead? or some ehci* driver. Look in /lib/modules/ for the available drivers.

Good luck…

I really hope you can help me
I am having a problem with a data card, I have been every where and can not seem to find the problem,
I had the router working great with an Option data card on vendor=0xaf0 product=0×6701
I have got a new E600 card, with the same setting as listed by you.
vendor=0×12d1 product=0×1001

I built and image with the old card settings, that I loaded onto a new router, and installed the new card in that one

But now i get the error as listed in DMESG
usb-ohci.c: usb-02:00.0, PCI device 1131:1561
usb.c: new USB bus registered, assigned bus number 2
hub.c: USB hub found

hub.c: new USB device 02:00.0-2, assigned address 4
usb.c: USB device not accepting new address=4 (error=-145)

How do I get around this as the card no longer initilases?
I am totaly stumped,

Please help??

It should work fine as a hotspot, but you may need additional software if you want to configure it for authentication. Such as Chili Hotspot.

Linksys has a list of supported devices, but it is rather short, and OpenWRT should support any PCMCIA 3G card that emulates serial ports. My huawei E600 isn’t supported by linksys, but it works fine with OpenWRT.

However, keep in mind that a cheaper choice may be to buy a normal wireless router with a USB port. I have several ASUS WL-500gP’s which should handle this fine. You can then buy a separate USB-based 3G modem. They tend to be cheaper then the PCMCIA 3G modems too.

Good luck,
Simon

Which of the WRT54G3G I have to buy?
I saw three flavors of this in Linksys site.
WRT54G3G-AT
WRT54G3G-ST
WRT54G3G-VN

Can use this as hotspot once installed with OpenWRT?
Are there any list of supported PCMCIA cards?
I’m from Asia, any online store I can buy this router?

That’s it for now =)

My WRT54G3G works fine with Kamikaze 0.9 and x-wrt. My data card is a Option Ge0301 with HSUPA. I followed the writeup of Simon. Then I had to change the usbserial.o to the new one to patch the small data rate. Now I get my fullspeed I got with the original Linksys firm.

Now one question. I miss a “dial on demand” function. I use a vodafone flat and I wish an auto connect. Has someone a solution?

Thanks a lot,
alex

I would Just like to thank you all (Peter, Simon and especially http://josefsson.org/) for all the write ups and how to’s.
I have learnt a lot, and built some interesting things.

Thank you again!
Cheers

I placed a copy at:

Naturally, keep in mind that in general you shouldn’t download untrusted binaries from the net and run them.

Finally, I have no idea whether this works or not, since I haven’t run across this problem.
