Colleagues,
I'm going to preface this by trying NOT to get emotional about what's become a very emotional subject for me. Here's the facts..
1) In mid-April I signed up for SkyTel 2Mbit wireless broadband out of Rosslare Harbour. After a month+ of battles to get the original installation working, a second installation finally resulted in upload/download speeds of approx. 700kbits.
2) Thinking this was a bit low I spoke to Garrett at Skytel about this; He said that there were 12 others on my VLAN and that it was due to contention. As I mentioned to him this occurred at 8am or 8pm, didn't seem to matter what time of day it was. He then "tweaked" my connection and IMMEDIATELY I was getting upload and download speeds of 1MBit and the response to the web was, well, fantastic.
3) Around the 15th of June, my speeds (both directions) dropped back to 700kBit. I didn't really notice it that much but I did notice that I was starting to get DNS timeouts and also timeouts on well-known web pages (CNN, eBay, Google, etc..). I also noticed that my IMAP mail client was starting to report "connection lost" to my mail server in Dallas, Texas, USA.
4) In the last week, the DNS timeouts got so bad that I had to switch from Skytels DNS server to the DNS servers at opendns.org, which solved the DNS timeout issues. Then things just got worse..
5) iChat started timing out with a colleague in Cork on a regular basis. Got so bad two days ago that we had to go back to ordinary twisted pair for our conference. Web pages started reporting that the server was'nt responding, etc.. etc..
6) So, I decided to run a ping every 10 seconds to my VLAN gateway (remember this is within SkyTels network, presumably) and to a well-known nameserver at esat.net:

As you can see from the stats above there was a whopping 13% packet loss in the early afternoon to MY OWN GATEWAY!!!
I then spoke to Michael (Garrett was presumably unavailable) and again, the same old story about "contention" blah blah blah and that everything looked "normal" from their side. Is this normal???
Now I fully accept that there is going to be some slow downs over the summer months with all the kiddies file sharing etc.. but honestly, 13% packet loss and round-trip ping times of 53 seconds is, in my opinion, a VERY underperforming network.
Oh, and Michael promised to phone back yesterday morning and I've yet to hear from Skytel yet.
I have a few beefs over all of this:
1) How can an ISP claim 2MBit symmetric connections when the link speed is clearly 700kBit?? I wonder if this is worthy of a complaint to the Dept. of Consumer Affairs or perhaps the Advertising Standards Authority.
2) I've been working with IP networks since the early days of the Internet and never have I seen a properly operating network return ping times of anything like 50 seconds even with heavy congestion.
3) The 13% packet loss looks like, to me, that intermediate routers are dropping 13% of my packets "on the floor" as they are never reaching my default gateway on my subnet. This would tend to suggest a very overloaded infrastructure.
The performance in the afternoon has gotten so bad that I cannot
a) Reliably send emails to my outgoing SMTP server. Sometimes it takes 2 or 3 tries to send a mail
b) Use iChat (about 10kbits bandwidth) for conferencing because of repeated timeouts (most times of the day).
c) Download large software updates (>5-10MB) as the connections time out along the way.
Is this really worth all the agro and should I wait or dump them now?
Suggestions?
Ron
