Cable problem

[blackslash]

hello I have a problem with my cable modem. I live in U.S and my cable modem gives me 5mbps of speed when I'm downloading but when I'm playing maplestory(The game I play) It lags insanely and disconnects alot but when I'm web browsing it never disconnects.

here are my tcp analyzer results

Search Google for SpyBot and Lavasoft Ad-Aware, download, install and update them.

Then reboot comp and during booting, press F5 and choose Windows 'Safe Mode'.

Scan and remove all spyware and malware with the said two programs.

I use window xp and I went to control panel and right clicked my network adapter and I picked properties and I didn't see any options saying speed and duplex plz tell me what steps I take

Control Panel -> System -> Hardware -> Device manager

Then expand on the 'Network Adapters' and click right on the name of your Nic and select 'Properties'

[blackslash]

well after I did what you told me I played the game a little bit better but the lag is still there(alot) and it doesn't disconnect as much but it still does.

Are there any more things I can do? Thnx btw

[trogers]

Do you have the same problem with lag and disconnects to some other game servers, or only to one particular server?

[blackslash]

it usually happens in any server

after I put those settings I couldn't even get in the game

Okay. Revert to the previous settings. My guess is that your singals from your game servers have quite a bit of packet losses along the way to you.

Tracert your server and see if your signals have to pass through any routers belonging to AT&T.

Make sure you modem is placed a few feet away from any other electrical devices to avoid being affected by electromagnetic interference.

[blackslash]

alright I checked my cable wiring and I didn't find too much near it jus removed a few little objects near it. theres nothing interfering with my connection.

[jeredish]

Make sure you modem is placed a few feet away from any other electrical devices to avoid being affected by electromagnetic interference.

On a side note what honestly would interference with the modem?

Now I asked this because I was under the inpression that if any EM interference would hurt the modem it was on the upstream more then the down stream. Just do to when your side has to shout at other things verses when it is getting shouted at.

Also the idea of an item effecting either of the up or down streams is a bit hard do happen if as long as you dont have a very very old cordless phone right by the modem correct? I mean the up stream is at 23 Mhz and the down is at 711Mhz.

" Initially, cordless phones used the 1.7 MHz frequency range to communicate between base and handset. Because of quality and range problems, these units were soon superseded by systems that used frequency modulation (FM) at higher frequency ranges (49 MHz, 900 MHz, 2.4 GHz, and 5.8 GHz)"

So phones really would have to be old to effect a modem.

"Except for 802.11a, which operates at 5 GHz...The frequencies for 802.11 b/g span 2.400 GHz to 2.487 GHz. Each channel is 22 MHz wide and there is a 5 MHz step to the next higher channel" this includes g and n aswell.

So the router cannnot really hurt the modem.

A standard Microwave operated around the 1 GHz area.

So my question is really unless your bleeding some sort of EM interference into the RF line, or you have some peice of electrical equipment that is really old by the modem do we really have to still pitch bogus EM Interference claims now adays?

The same ideas are touted by the new technicians of cable, or DSL companies but they need to realize that most equipment that would be around a modem now a days will not cause such problems.
