I no longer have a Linksys product as I had a router go down, which they replaced with good grace, but the replacement only lasted a month. I since bought a Netgear and all has been well, but I digress.
One thing I would say, is that while I was using Linksys, I didn't actually use the telephone helpline, but I had extremely good support through the 'Live chat' system. I used it on 3 or 4 occasions, and on each one I never waited more than a few minutes before being connected.
The obvious issue is you need internet access to use this, so depending on your situation the phone may be your only option.
It's a shame about this, as I did find their staff genuinely helpful.
