We had 1 router and 1 cable modem (WRT54GS v7 and SB5120) for our apartment. When I would download, the others would receive very high network latency, thus Cox came out and installed a second SB5120 in my room (thus different outlet).

I have been on my own Cox account and line for several days now with minimal network latency, and have been able to download fine, but my roommates with the setup listed above still experience lag, but not nearly as much. (Yes it's not the in game host lagging =p).

Is this because the Coaxial lines in the apartment run on a bus infrastructure to the street? Is it my network usage that is lagging them (I've been using 100KB down and 60KB up consistently). and I don't know about bandwidth and latency of coaxial either...

Thanks!

The coax could be a problem. Is the apartment building wired with RG5? If so, then it will hinder it, also, any opens or shorts or any physical damage to any of the cableing inside the apartment building or in the distribution panel itself could cause problems.

The company itself would have to locate and identify the culprit.

By the company, would that be Cox Communications, or my landlord The Irvine Company?

the problem could be that the internet is shared on the incomming line..meaning that everyone in the building is getting there internet off the same line and then its split between the apartments...once one person starts to eat the bandwidth then everyone else thats late to get on will suffer...thats the only problem with having a cable connection with a bandwidth (monster) near the neighborhood...lol

That was my understanding of the issue because it's a bus implementation. I might ask a couple of the guy apts if they get gaming lag.

The leasing office here is checking on the coax cable std (the cable is unlabeled in the wall).

But at the bandwidth rates I posted, should that really lag the whole line?

What is the bandwidth of a RG-6 or RG-8 coaxial cable, whatever is in an apt, or the main line going to the street?

All coax labeled as RG has to pass 75ohms. The cable plant works off of 75ohms, the RG59 cable is generally older and is usually replaced by techs if they see it in use. Now an MDU (apartment building) they may not change it ouyt because it would require a complete rewire.

Now if there is only one tap serving your entire building (how many tenents are their) and this drop is only RG6 then you are going to have problems. If they used 320 line then you would have better signal strength in the building. Seeing as i don't know where you live, what the plant looks like or how far you are from the ped/tap i really can't get to specific.

Ok, so the lag still happens when I have my modem turned off.
I should note that they only started lagging once they switched from my equipment to theirs,
SB5101 Cable Modem
Level One WBR-3406TX Router

and when the Cox tech came out, he said the signal levels on both modems were fine...


**EDIT: I believe it has something to do with the wireless on this router because when the he is plugged into a RJ-45 jack, he experiences only the normal network latency, but if he switches to wireless it spikes all the time. It isn't a frequency issue either.

Sucks for them...

Thanks!
Anyone? =)
