Pacman -Syu killed network performance

My system was mostly working fine, and I went on vacation for 2 weeks.  When I got back, I did a pacman -Syu (about 4 weeks worth of updates).  A lot was updated, and my Internet connection is unusably slow, but nothing else appears to have broken.  Google's search page takes 2+ minutes to load, and an actual search takes longer.

I have a netbook, so I am sure this is a problem with my linux box, and not the router, cable modem, or cable company.  CPU and other resources don't seem to be used.

I was (and still am) manually bringing up my network connection with dhcpcd when I rebooted before this problem happened.

I essentially do not have a network on the machine affected, so I am limited in what I can do to troubleshoot this.  I have not been able to get another pacman -Syu to update successfully due to this issue.

Working for an ISP, I can assure you that you can never be sure that it's not your ISP.

Give us some results of ping and traceroute to sites that refuse to work. Also ping your router to see where the slownes happens.

Re: Pacman -Syu killed network performance

With the netbook doing a google search well over 100 times faster, it is not the ISP.

Re: Pacman -Syu killed network performance

The problem is definitely between the Arch machine and router.  I can ping localhost normally.  pinging the router takes anywhere between 100 and 10,000 milliseconds.  Pinging the router from the netbook takes 10 milliseconds.

Re: Pacman -Syu killed network performance

I am trying to do another Pacman -Syu.  Does anyone know of a way to increase the timeout?  With partial downloads, packages eventually finish with multiple attempts, but the are being updated faster than I can download them.

Re: Pacman -Syu killed network performance

Fixed the problem by lowering my router speed.  I still wish I knew if this was a firmware, driver or other problem.

What in the world is "lowering my router speed"?

Re: Pacman -Syu killed network performance

If he was using testing, a pacman -Syu would upgrade to 2.6.37, bringing a host of network drivers with it. If he was using wifi, something like the carl9170 (replacing ar9170usb) driver could change things substantially, and existing config could turn everything FUBAR.
