Clearwire problems with Skype

    To all clearwire users (and to tech support if they're looking)

    I have got clearwire BB for 2 weeks now and it's working great, I'm certainly getting the speeds I expect.

    However, I'm not getting a great experience with Skype so far, but I'm not sure if it is my connection or not. Calls to echo123 have a lot of distortion/cutting out etc, so I'm worried that it is my connection. I don't know how the wireless environment should affect skype.

    How is everyone else's experience of using Skype or other VOIP services with Skype, I would be interested to know!

    I am in Sandyford.

    Thanks,

    Jonathan

    Seems to be a little better now actually, when I tried a SkypeOut mobile call

    Call Customer Service and get them to "tweak" your connection for VOIP, certainly worked for me.

    I vaguely remember reading about clearwire in the US and how they blocked some VOIP services from competing companies (eg Vonage in the US). I'm not sure if that's what they're up to in Ireland too....http://news.com.com/Vonage+says+Clearwire+interfered+with+VoIP+calls/2100-7352_3-5657386.html

    Looking around I came across one or two other bits....

    http://blog.pff.org/archives/2005/04/voip_blocking_t.html

    And perhaps most tellingly from the Skype forum...

    They're not blocking VoIP in Ireland.

    Your problems are probably because of packet loss or very high latency. In my [somewhat limited] experience packet loss is the main killer of VoIP.

    The do not block VOIP. I was using Skypeout earlier this evening.

    More than likely your packet loss is so great that skype isn't worth using, as has been the case for a few days now on Clearwire :(

    Haven't had any problems myself. I use VoIpCheap (voipcheap.co.uk) for calling land lines in Ireland, Google Talk or Skype for calling friends pc's, and haven't had any problems so far. There was one incident the other night, when my ping response time shot to 400-500 ms to my gateway for some reason, but this only lasted 20-30 mins, and is now fine again.

    Doesn't make sense eth0. Where are you living exactly? I'm on Haddington Road, and am connecting to FitzWilliam Square. Here's my response times to boards at present:

    Latency is relatively high to boards, ftp.heanet.ie and default gateway, as you can see (Also jumps up and down a good bit), but nowhere near 1000 ms!! That's just nuts!!
    Have you been onto the support team about it?

    I live 2 blocks behind Camden St, near the Meath St hospital.

    They told me i'm on the Harolds X transmitter.

    It looks to me, from the traceroutes, like they don't have the backhaul for all the extra customers who've jumped on board the past few weeks.

    I should be on the 'pro' package, perhaps i'm not. What package are you on?

    Yes, I have contacted support, last Thursday in fact. They ask me for my modem serial number. I don't see what good that is. They've already replaced my modem since I started using Clearwire. They still haven't been able to answer my question as to what package i'm *on*, since they went and replaced the one I signed up with originally with a different package!
    Nor have they provided me with an invoice like I asked.

    Worrying.

    See, it's back to normal now, at 7am when there's not many using the service.
