Satellite TV system reduces Internet speed

With my new Internet speed (up to 6400 kbps down and 520 kbps up), I had found that there was a major interference from the Sky satellite system which requires two phone cables from the main phone output box to each of the two Sky boxes that we have.
When the phone cables were plugeed into the TVs, Internet d/l speed droped from about 6200-6400 to 300-3200 kbps.
However, the problem was easily resolved.
I bought a Advent ADSL filter for €10 and inserted it in the main phone socket. The line that goes to the router I placed in the ADSL outlet of the filter. Then in the phone outlet of the filter I placed the "tripler" that had previously been in the main phone socket. Into two of the tripler outlets I placed the two phone lines that go to the Sky boxes.
Note that the line from the ADSL outlet actually splits to both the router and a phone.
Nevertheless, this arrangement exactly solved the problem. Now, even with the phone lines hooked up to the two Sky boxes, Internet d/l speeds over 6000 kbps are obtained.

Faster and faster internet

Spoke quite a few times to my ISP (Eircom) as to why I was not seeing a consistent 3 Mbps d/l rate. The guy claimed that it our Sky satellite TV (which is hooked up to phone lines) may be interfering with the signal which he said was very noisy.
So I disconnected the phone line from both TVs, whereupon the guy said that the signal became steadier and clean. He recommended putting an ADSL filter on each of the phone lines to the TVs.
He then said that everything was ready for my line to be upgraded to 7.6 Mbps and I would start seeing this in 10-15 minutes.
However, even after 2 hours, the best I was getting was still below 3 Mbps.
So, on the phone again. This guy said that it had never been set up for 7.6 Mbps but he could do it right now. So, he did and the speed actually did go up to in excess of 6 Mbps with about 450 kbps u/l.
Now some hours later I'm still getting this (with phone line to TVs disconnected). Just right now I measured 6138 kbps d/l and 500 kbps u/l. However, it seems the router needs to be rebooted every now and again.
But, although the situation is not troublefree, at least things are moving a lot more swiftly than they were at the start of the week. Indeed, right now, I don't know how I could have put up with only 1600 kbps just a few days ago (and worse, 1 Mbps a few years ago).

Internet upgrade

I've been using Eircom Home Plus for a long time. Its download and upload speeds (actual rather than what they're supposed to be): 1650 kbps/200 kbps.
I had talked quite a bit to Eircom as to why I wasn't getting the advertised 2048/256 speeds and they claimed that anything upwards of 80% of the nominal rate was considered OK. They claimed that distance from the exchange mad a big difference to what actual speeds were attainable.
In any event, they have been promising that this package (Home Plus) will be updated before the end of the summer to 3072 kbps but that hasn't happened yet.
So, yesterday, I upgraded to Home Professional which has advertised speeds of 3072/384. What's more, this package will be upgraded to 7782/672 sometime very soon (they even said it might be this week).
In any event, my speed went up today. First to something like 2150/470. So, as it hadn't reached to where I expected, I called them and, after looking at the data, they concluded there was an error in something or other. They fixed this quickly and I immediately starting getting speeds of 3150/285. So this was a huge jump and I was very pleased with this, particularly as an even greater jump was likely very soon.
It's interesting to note that the attained download speed was actually GREATER than the advertised d/l speed of 3072 kbps which might suggest that whatever my distance from the exchange it shouldn't prevent me getting a high d/l speed.
Another possibility becomes obvious looking at the d/l&u/l speeds attained in the two instances quoted: 2150/470 and 3150/285 versus advertised of 3072/384. This seems to indicate that they can fiddle around with the upload/download speed combinations. So, if upload is high, d/l comes down a lot.
Anyway, these good speeds persisted for a couple of hours and then, without warning, both deteriorated. Right now we are getting 1800/270. Looks like I'm going to have to talk to them again tomorrow.

Finally, Haiku coming to life!

Well, a lot of positive changes today.
First, I downloaded a newer version of Haiku's daily build (from 18/02/08) and found that I got an Internet (wired) connection immediately on boot. So, a huge step forward.
Then I tried to install Links (text browser) from this link (bottom of comment posted on 15-02-08) and this worked fine although Links takes a bit of getting used to for anybody accustomed to GUI browsers.
However, in the same link as above I saw that there is available a weekly-updated Haiku super-pack that is expandable to 1 GB HDD size and has quite a lot of apps and other stuff included in the package. Get this from here.
Now I did this and installed but couldn't get an Internet connection with the latest super-pack.
So I downloaded an earlier version (Feb 9) and same result--no Internet.
I noticed also that those Haiku's that gave an Internet connection (actually only one up to this point) gave a broadcast address of 255.255.255.255 while all the others gave something like 192.168.1.255.
Then I made a dramatic discovery: trying out one of the super-packs, I noticed that the network was set as Nat while the only one version that gave a connection was set at Bridged.
So, I changed from Nat to Bridged (goto Dell page, edit settings,set on Ethernet and change from Nat to bridged).
Internet connection was immediate and the broadcast address changed to 255.255.255.255

Before I discovered that the super-packs could have Internet too, I downloaded Opera (for BeOS) 3.62 in the Haikuware site (on the Mac). Then, as the file was only 2.05 MB in size, I transferred it to the Dell using cl1p.net (which is supposed to take a max file size of 2 MB but took this slightly larger one without complaint.
This was a .bin file and the way to install these is:

1) Go to directory where the .bin file is
2) chmod +x filename.bin #make the file executable
3) ./filename.bin #now it will install

So, all-in-all, a very successful day although the Opera version and that of Firefox in the super-packs are very clunky and difficult to use. What's more, you just can't get to your personal iGoogle in either browser.

Still struggling with internet connection to Haiku

What I have found is that:
1) I can ping to the local host (127.0.0.1)
2) I can ping to the OS IP (right now it's set at 192.168.1.0)
3) Cannot ping to anything else

Another thing I found is that the Network Preferences box seems to go back to Static from DHCP when I shut it down. I thought that perhaps, as my router is not set up to accept static IPs, it was getting confused with this and this was the reason for me not being able to get an Internet connection.
Still asking questions in the forums but getting few answers and , up to now, no valuable answers.
