Using 15.04 (beta2) and I have problem with wifi connection. It is too slow, and after a few minutes it just disconect and I can't connect back again.

I managed to make it work for Linksys WMP54G v4.1. Hope this would be helpful. Download the Ralink Wireless LAN Driver (PCI/mPCI/CB RT2500). Aug 15, 2015 When I tried to upgrade, Setup said my Ralink RT2500 PCI wireless card was not compatible with Windows 10. I removed it and.

(bool) I know the rt2500-, rt61- and rt73-series is a bit twitchy and troublesome but I can't seen to find a solution to this problem.

I've just been reading around on this for you and it seems this is a very common problem with this particular brand of wifi card. The most common solution that seems to keep popping up is to install the actual MS Windows driver for this card using something called 'ndiswrapper'. I used to use ndiswrapper all the time back in the days of Ubuntu 10.04. But have found, since ubuntu 12.04, that it has become more or less obsolete due to improvements in driver support from Ubuntu. This particular card, however, seems to have slipped throught that particular net. You can install ndiswrapper from the software centre and there are plenty of guides on the internet on how to use it.

I hope you can get it fixed mate, because I do understand there is nothing more frustrating that a wobbly internet connection. Failing the above, one cast iron way to get your internet working is to use something called powerline adapters. These link up your ethernet card to your mains wiring system, via a standard plug socket, to your internet router, whoch is connected to your mains wiring by the same means. It's more or less as fast as standard ethernet cabling, but is a hell of a lot more convenient due to the mains wiring being already hidden and in place around your house.

Drivers Diebold Procomp Im4x3tp. The only caveat to the above solution working is if your PC is on a different floor in the building than your internet router is on. This is becase it would mean the powerline signal would have to go though your electrical junction box to get from your downstars mains ring to your upstaris one. Unfortunately, there is too much electrical noise occurring at the junction box and so the signakl would get scramled.

Thus, if you have a situation where your internet router is on one floor, but your POC is on anotehr floor (and so using a seperate mains ring, the solution is to run an extension lead form your router's ring mains to whereever your Pc is and then run your power line adapter on your PC to that extension. Thus, ensuring that both your PC and internet router can communicate properly.

Or, alternatively, simply relocate your router on the same floor as your PC if you have a telecommunications point on that floor. A better illustration of how powerline adapters work is below: I can personally vouch for these as I use them myself in my own home following similar issue to yours with my wireless card.

In my case, the RTL8192ce. It would mean spending about the same as you would on a new wireless card for the pair of powerline sdapters you would need (about 25 quid for a pair of adapters in the UK) However, their advantage is that they are guaranted to work as they directly communicate with your ethernet.

No drivers or any other software required. They sound too good to be true don't they.I certainly thought so prior to buying a pair. However, since doing so, I haven't look back. Thanks for the tutorial! In my case, it is not only disconnecting but the connection it is really slow. I know this is due to my wifi card, because I already faced this problem when I was using Antergos. Thanks for helping me!

I've been through this problem in other distributions, but in Ubuntu Mate is the first time that at least the wifi connection is connecting. In other distributions the wifi connection do not work because of my card. I had never heard of powerline adapters. Maybe that's the solution to my problem if all else fails! I will try to install 'ndiswrapper' (in which I have yet to find out about) and post the results here. Once again, thank you both! I'm having the same issue with rt61pci.

The problem started when upgrading from 14.10 to 15.04 April 23rd 2015. Kernel 3.16.0-34-generic to 3.19.0-15-generic. In Ubuntu 14 the only issue I had was WiFi not working after sleep. I tried ndiswrapper using the drivers from: 'PCI/ mPCI/ CB(RT256x/ RT266x)' (Use wine to run exe, which will extract the driver, then browse drive_c for the inf file) The Windows driver works, however, it also disconnects after a minute or so. I've tried the nohwcrypt=Y option and sudo iwconfig wlan0 power off Suggested here: Still no improvement. Removing all wireless modules and modprobe again would get WiFi working for about 1 minute. #!/bin/bash echo 'rmmod.'

RMMOD='sudo rmmod -v' $RMMOD rt61pci $RMMOD rt2x00mmio $RMMOD rt2x00pci $RMMOD rt2x00lib sleep 2 echo 'modprobe.' Sudo modprobe -v rt61pci nohwcrypt=Y I booted into Ubuntu 15.04 live using a USB stick and verified the WiFi still disconnects after a minute. Nero Vision Portable Ita Download Movies. I booted into my old kernel and still have the problem.

I also tried upstart mode for both kernels. At this point I've given up, luckily I have a usb WiFi (using rt2800usb) that works fine. If anyone has any more ideas to try, let me know. In Ubuntu, I installed linux-firmware; it seems like it installed the right firmware file: /lib/firmware$ dpkg-query -S rt2561.bin linux-firmware: /lib/firmware/rt2561.bin This seems to indicate it is in use: $ modinfo rt61pci filename: /lib/modules/3.19.0-15-generic/kernel/drivers/net/wireless/rt2x00/rt61pci.ko license: GPL firmware: rt2661.bin firmware: rt2561s.bin firmware: rt2561.bin description: Ralink RT61 PCI & PCMCIA Wireless LAN driver.

(bool) I thought I already had this installed and it didn't make a difference, but right now WiFi has been up for 10 minutes without going down.

So it's working better today for some reason.
