512k Broadband from terranet

recon1025

Hi guys, I just had my 512k installed today. The cost is ridiculious and the service isnt that great. Anyway, I got a question. The technician who installed the unit on my roof used UTP CAT 5e cabling from the switch down to my apartment, about 4 floors down. However he did use STP CAT5e from switch to the SSU4000 which is the antenna unit. Anyway I argued that UTP is really bad to be run outside, its mainly used inside where u have no wires what so ever. Since UTP is affected by EMI (Electro Magnetic Interference) anyway I was just shocked to see that some people still use UTP and it pissed me off. The guy was no network expert, he was an electrician. Anyway now that everything is setup properly. I try pinging the antenna on the roof with my pc and the round trip from my pc to that unit is jumpy, it goes from 1 all the way to 25ms. Now ive majored in networking administration and I got a feeling the utp is causing problems because there's no way a ping from a unit thats a mere 50 meters up is going to cause lag!! I get reponse times up to 25ms from the antenna on the roof, I believe thats ridiculious it should either be 1ms stable or 10ms stable. Thank you for reading this lengthy post and i'd love to hear your educated opinion.

I somehow got him to put the receiver and the switch in my appartment and use STP from the roof to my appartment (3 storeys down) :)
He wasn't very happy about what he was doing, said that the STP was expensive.
I wonder if 12 meters between the antenna and the receiver box (the small black box) is good.
Anyway it wouldn't make any difference with their crappy so called broadband. Heck in egypt they have better ADSL for half the price. I wrote a post on my connection here:

When I ping the "gateway" (ip of the ethernet interface minus 1), i get an almost constant 0.930 lag sometimes 1.1 ms. I'm assuming the gateway is the antenna.
When I ping one of the terranet routers (212.98.136.33), I get
rtt min/avg/max/mdev = 32.383/45.653/87.106/11.124 ms
that's a ping of around 40ms

Now the recever unit (the small black box) is directly plugged into the computer, no switch between them. I understand you have a switch in your setup. If there are other computers on the switch, and they are infected by some virus that causes massive ping scans, it can slow down the swithch.

By the way I have no computer science major, but would like to work in the field of internet and networking. Any tips? I'll complete a business computing major soon.
What about CCNA?
Where can I find jobs?

I have an UDP cable running from the basement to the 2nd floor. that's about 12 meters.
At first, I had wired it incorrectly and it did barely worked. When I rewired it linke this:
FROM LEFT TO RIGHT, looking at the plug from the side of the connectors:
white-orange, orange, white-green, blue, white-blue, green, white-brown, brown

Now it works fine at 100mb/s
If you're having problems, try swithching to 10mb/s mode, it's much more reliable.

By the way, you might want to put lightning protection on this cable, it may grill your PC.

changed my mind, deleted my post... sorry

oh yes.... happened to me b4.... i had to buy a BRAND NEW pc, coz of the damn thunder...EVERYTHING was dead inside, board, slots, cpu, EVERYTHING !! now i installed an SDP cable, it's not 100% better, but at least some protection..

Thats a pretty good connection , how much does it cost u and is it dedicated 512k or shared? And do they limit you to a given bandwidth?

rolf

Hi dude.
No, transfer quota is not limited. Ya3ne you can download as much as you want.
It's shared, and pretty crowded, ya3neh you rarely get the maximum (55KB/s) But you get minimum 35KB most of the time.
The simutaneous connections are limited to a maximum of approx 23 TCP connections, ya3ne you'd better use it only on one computer, and if you use file sharing you have to be careful not to download too many files at once, or else connextions will start to be refused.
I am deceived because I never got more than 8-9 KB download on kazaa, and the upload is not faster than a modem. but the rest is pretty cool.
Try to see someone with a idm connection before deciding. I have a feeling that IDM have a better quality (just a feeling....).

I wrote about this connection in this post too:

yeah happened to me too, struck 2 PCs at once: the 1st pc (a special small barebone PC) was completely grilled like you said, and the reseller talked his way out of applying the 1 year warranty
So, DO NOT GO TO TELETRADE - he wont replace your PC if it fails.
The 2nd PC is a reagular computer with an MSI board, only the onboard LAN was damaged. The rest of the PC was ok, I just had to plug in a new 10$ network adapter. But maybe that's because PC n.1 took all the shock.

I didn't know SDP (you mean STP?) offers protection.

Anyway I got special lighning protection equipment. It's a tiny plastic box that you put between your network cable and PC (or switch) and it will stop the current from passing if the cable is struck by lightning. It costs 15$ I think.

hi
i have some problem ive been trying to get fast internet but cant find so the lest company i got was gds and they give me account on cyberia i got 128k cable 50$/month

i thought i would go at 60-70 kb/s but its like 10-15kb/s and kazaa is even slower

wtf is this is this speed normall cuz i was in dubia first and dsl is cheaper and goes from 60-80kb/s

Ragnar78

when they say 128kb it means kilobits and not kilobytes...
so when you get a 128kilobits, divide it by 8 and you get the bandwidth in kilobytes...

2 month ago i installed ADSL2, its a 20meg connection, almost 1,2 meg transfer for 30 euros...i also have freephone and 80 TV channels for free and all for 30 euros....

man rangar ur soo luky here its about ripping ppl off and fuking them u never get any good service

Internet in lebanon is heavily taxed, and there is not much competition, so you wont get anything good.
In the US they started commercialising a cellular system that lets you browse the net on your cell at 192kbit/s (i think). Of course it's cheaper than our 128k.
Soon they'll have broadband on handheld devices in the outsite, on laptops, ipods, cells, pda's... I wonder were we'll in lebanon then.

I checked satellite prices, they're still quite expensive. But if you dont download much, you can have a cheap satellite connexion with a limited transfer quota, if speed, not volume is what matters to you.

By the way tell me how is the quality of cyberia? How fast on kazaa?

Well actually, their is no infrastructure to support ADSL in leb. This is why it cost so much over their...the companies have to install everything. Other then them being rip offs, they still have to put the infrastructure for it

Any idea where i can get one of those? and yes i meant STP, sorry by mistake

rolf

Nope, the place where I got them was out of stock last time I checked.
I'll tell you if I find something.

TSOG

You guys want really fast internet? Apply for a legal Showtime subscription. I'm telling you, it's awesome. You get internet for free once subscribed, but if you want something as fast as 512, you'll need to pay up just a bit more. Bottom line, legal Showtime + 512 internet would still cost way less than what you're paying right now. Oh, and there are NO installation fees. Peace out!

i just wanna say on kazaa it sux 4kb/s and sometimes it doesent even connect just says looking for more sources
