Ralink RT2561 Driver and Firmware for Windows and Linux and Mac OS. Windows server 2012 r2 activation key. The utility will automatically determine the right driver for your system as well as download and install the Ralink RT2561 driver. Being an easy-to-use utility, The Drivers Update Tool is a great alternative to manual installation, which has been recognized by many computer experts and computer magazines.

I recently installed several versions of the haiku-nightlies (most recently 40448 gcc2-hybrid), but i can’t get the ralinkwifi driver working. The card is ok, i had it working under several other (mostly useless) os-es. Ok so my device is being reported as “device 0301: RT2561/RT61 802.11g PCI” by listdev (full list here: ), and the kernel reports the following error into syslog (more here: ): KERN: [ralinkwifi] (ral) bus_alloc_resource(1, [0], 0x0, 0xffffffff, 0x1,0x6) KERN: [ralinkwifi] (ral) could not allocate interrupt resource the machine is a packard bell easynote r1004 laptop, some 4-5 years old, it should be best for some haiku geekness any help is much appreciated. [quote=NoHaikuForMe]The log shows this device doesn’t have an interrupt line assigned. Haiku’s PCI code reports it as line zero, which means none. To get the device working it needs an interrupt, most commonly the BIOS will do this assignment during startup, but Haiku also needs to be able to do this at runtime. It’s possible that you can work around this by tweaking BIOS options labelled e.g.

“PnP OS” or by manually assigning the IRQ line if there’s a feature which lets you do that.[/quote] well that’s the worst part of all, the bios on this laptop is the lamest one i’ve ever seen, it has only options for boot order, date and memory allocated to the videocard. I already searched for a bios upgrade but this machine is ancient, and i don’t believe the upgraded version has more features. Is there any possibility that the OS can do this irq assignment? (or do any of you know some other way around this?) I mean either inside (maybe some parameters for the driver or the pci code) or outside Haiku (I’m not much into custom bios hacking but there may be something out there). I have seen few people able to resolve the IRQ issue by disabling their wired network card.

Sometimes an IRQ conflict happens for some people. To see your IRQ list, in terminal type: kernel_debugger then ints you will see int X, where X=0 to 15 plus any device using that IRQ then type exit to leave You can disable wired card (and audio card too) by removing their drivers from Haiku. Then they won’t take up any IRQs. Maybe you get lucky and then WiFi works. Why not use your wired network? Seems your wired network card was detected but dhcp was not working for you.

There was a dhcp issue recently fixed in 40492. Get a newer nightly. Ok i updated to 40501, i looked at my irq list, and practically removed every driver i could (including usb, ps2, audio, wired network), but sadly nothing helped, the wifi card still reports the same error. Btw, there’s a line in the syslog which i don’t understand: KERN: ioapic explicitly disabled, not using ioapics for interrupt routing maybe enabling this feature would help me?

I’m not using the wired interface because all my other devices use the same wifi router, so i had to pull the cable off my wifi router to download the optional packages (and the firmwares). [quote=gif]Btw, there’s a line in the syslog which i don’t understand: KERN: ioapic explicitly disabled, not using ioapics for interrupt routing maybe enabling this feature would help me? [/quote] Yes, but no. Having working interrupt routing would help you, in that then your WiFi could work. Having IOAPIC support could be a step in that direction. But as far as I can tell Haiku’s IOAPIC support is “explicitly” disabled because it simply doesn’t work.
