I'm having some wireless / router / DSL / Bandwidth issues - help me solve this scenario....plz

[TheNinja]

Ok here is my setup:

Downstairs: My neighbor downstairs has DSL. I bought a 4 port router/switch. The DSL line goes into the router. He has one CAT5 cable running from the router/switch to his computer. I have a Wireless Access Point (WAP) connected to another port of the router/switch.

Upstairs: I have another WAP in my room (the WAPs are setup to talk only to each other). Then I have a CAT5 running from the WAP to a 4port switch and I run my two computers off of the switch using CAT5

PROBLEM: Everything works great, until he turns on his computer and starts downloading stuff. My bandwidth goes to complete crap and even browsing the Internet seems like I'm using a dialup (only slightly better). And you can forget about playing BF1942 online b/c the pings are around 500-1000 on average.

Solution: I have access to all settings on the network/router b/c I set it all up. Can I cap the bandwidth for each IP address or do anything to resolve this?

my initial thought is. I have no idea why this would be the case, but it seems logical that the data will take the path of least resistance (so to speak) and since he is running direct from a cable to the router, the router gives him first dibs on the bandwidth leaving the WAP path (more resistance/time) with the leftovers.

His large packets consume almost all of your DSL bandwidth, with your very small packets getting delays significantly.

Look around for linux solutions that may be able to limit the downloading somewhat.

You mean linux might have solutions that I could limit the d/l bandwidt based on IP? Because that would be perfect....I look all around the router settings (It is a linksys) and couldn't find anything like that.

I've seen this scenario many times and have fixed it many times by limiting the bandwidth hog machine. Change the NIC setting on his machine to 10 meg half duplex. It will balance out your load again.

wow, no good solutions here at all.

well except for looking into linux to limit bandwidth. but then again you would need to get the linux machine between his and the dsl connection.


changing his nic to half duplex is not going to help (10mbs versus 100mbs? still fast enough to saturate a 1.5mbds dsl connection).


You cna look in at the router settings but i have yet to find one/hear about one that has a setting about bandwidth throttling.

Maybe you could go speak to him about his downloading? Thought about that? maybe hes got file sharing on and he coudl reduce it in their settings.

The 'path of least resistence' that was mentioned is just dumb. Though you do have many points of potential latency in your setup (all routers, etc) if it only gets affected when he turns on his computer(how are you so sure of this?) then that is not the problem.


a perfect solution: get yoru own DSL.

On a 1.5 Meg DSL : Machines set to 100 Meg full duplex crank at 150K sec.

Machines set to 10 meg half duplex run at half the speed (65K sec) , is that enough proof?

Setting it to the half duplex throws in like a sort of wait state. I see it work.

Do a DOS attack on his PC.

j/k.....what kind of Router is it, anything manageable?

 

[martind1]

where are these numbers coming from?



further more, thats nto a good solution, since it does not pay to be sneaky in a situation liek this, he coudl turn it back on full.


further more, if you don't like it, BUY YOUR OWN.
people are quite cheap sometimes.
