configuring modem/router settings for gaming/bandwidth

[ara ara]

main modem router - cisco DPC3825
bridge router - DIR-600
Laptop for gaming (Dota2) - connected to modem via Ethernet cable.

so main modem ports - lan1 - laptop; lan2 - router

scene 1:
Laptop connected to modem only
INGAME PING: 40-50ms (okay)

scene 2:
Laptop and bridge router connected to modem
INGAME PING: 40~3000ms


I can't pull out the connection for bridge router for it is used throughout the home.

How can i configure the settings of the modem to improve my ingame ping while both my laptop and the bridge router are connected to the modem?

If you can connect to the cisco to play either way (wi-fi or ethernet) don't bother with the router. It doesn't matter what port you're in they'll send the same connection.

It also isn't going to matter what you connect to if the network is busy with people on it using it heavily the same time you are. It might help if you connect to the main router to game if eveyone and everything else is connected to the "bridge router".

The cisco has wi-fi too. If the d-link router is physically sitting right next to the cisco modem/router there is absolutely no reason to have 2 routers.

hi jack,

thanks for clarifying the lan ports, i thought there was some kind of bandwidth allocation prioritization with those, but anyway, i think my question was unclear.

im getting a decent and stable ping on dota2 while playing with my laptop connected (ethernet) to cisco (main) only, dlink (bridge) is disconnected, i did those because i want have a reliable ping.

cisco is installed in my room upstairs, this modem have weak wifi so we decided to buy the dlink and bridged it and install downstairs. they notice the dlink is not active, so i connect it back to cisco. then my ingame ping goes high and very high.

are there any recommended settings to do on cisco so that i can have the stable ping back while dlink is active and feeding to other devices?

You're using DLAN aka LAN over power cable right? Those are hit or miss. Especially when not being on the same breaker circuit.

Make sure the wi-fi networks are named different names. Make sure all wired connections to any wired device are securly clipped in their socket/port. And make sure devices aren't bouncing between them constantly.

There is a way to give priority to specific devices on a network and that's called QoS packet scheduling but with what you're describing is going on doing that isn't going to help.

Do you have a broadband or a DSL connection?
It could be from that too if it's DSL.

I've been doing computer networking since well before the internet was released to the public. For those that didn't know, to give a short little history, networking has been around since the 1960s. Networking started being developed in the 1950s.

The term "bridge" is when you combine two different incoming connections to make them one, or use a computer to share the internet/network connection it has access to with other computers and devices letting other devices connect to that computer instead of the main connection. When you use a router as you're describing it's called an access point also called a range extender. You're using the d-link router to extend the range of the wi-fi? That term for the d-link router is access point. If it's being used to plug other devices into it like a printer or NAS (Networked Accessible Storage - a hard drive everyone on the network can access) then calling it a bridge is the correct term. The term bridge is also used other ways but I won't get into that. I'm trying not to write a book here but I also want to be informative and thorough.

Do you really have a bridge? Or is the d-link an access point?

A wired connection is always going to be a better, faster, more reliable connection than wi-fi. Are they saying the d-link is "inactive" because the lights aren't doing anything? The lights should be flashing as it sends and receives traffic. The lights on the Cisco should do the same thing (flash when there's traffic / it's working) that's how all routers work. If the lights aren't flashing that means there's no traffic - most likely because nothing is using it. Are you sure people are connecting to the d-link and not being either bounced to or connecting to the Cisco? That could explain why it doesn't look active but doesn't explain why when you connect the d-link up to the cisco the connection goes splat.

What can explain that is one of them is faulty and not working properly. OR - like you're thinking they're not configured properly:
· Wherever the connection comes in from the pole from the power company should go to the modem which you're saying is the Cisco. Wi-fi devices up stairs should be able to use it's wi-fi.
· The d-link down stairs should be wired from one of the out ports on the Cisco to the Ethernet/Internet in port on the d-link router.
· The home will have 2 wi-fi connections. They need to have different names, and different connection passwords.

If some devices are always downstairs, forget the login info on them for the Cisco and vise versa - devices always up stairs, forget the login info for the d-link wi-fi.

A router, which is all the d-link DIR-600 is does not receive wi-fi signal it only sends it. A router can be used as an access point but it has to be wired to the main modem/router. Both network names, the names you see when looking at a list of available wi-fi connections on a device, should be different. If they're not different it's possible they're getting confused and and arguing with each other and sending wi-fi devices back and forth between both of them constantly which will bog the connection quality down. That could be what the ping spikes you see are from, other devices getting thrown out and re-connecting.

The spikes could also be from interference but I think it's more likely what I just expained or the Cisco modem is giving out. If one of the routers is faulty I would first accuse the Cisco because in my experience I've found them to be consistantly faulty. I've had a d-link DIR-615 router for 20(?) years now and it's still my main router, still going strong. If I had a dollar for every Cisco (which is also Linksys, NetGear, and Belkin) networking device I've found to not be working right and replaced with a d-link over the years I'd be a millionare. It's not impossible it's the d-link that's faulty but I would be surprised if it is.

I honestly don't think either of them are faulty. I think it's that they're getting whipped and spanked by connection bottlenecking and arguments and constant disconnects and reconnects.

This was a lot longer than I wanted it to be.

Thanks jack. im new to these things, and im grateful someone is helping me to learn.

The two Wifis named differently, also im the only one knows the password for the main.

Broadband cable connection.

i read how to avoid interference by selecting the best available channel.

Access point it is. thanks for explaining that one.

1. yes, also tried the wifi of main completely disable
2. yes.
3. yes.

=========================

im playing from the main via wired connection to my computer.
once i connect the port dlink to main, that's when the problem starts.

hmmm.. ill try to isolate the dlink and connect other devices to the main via wireless and check if my ping is unstable.

The channel selection only effects wi-fi and one wi-fi connection can interfere with another. That's possible. That's primarily what the channel selection is for. The channels you have selected on each router might be the interferecne. Try and test different channel combinations.

The d-link seems to be doing what it's supposed to. It's the Cisco that's crapping out when something's plugged in to it. If the Cisco is through your provider contact your provider and ask for a replacement. If it's one you bought personally, get one from your provider and use theirs.

I looked that modem up and saw that on amazon it says service providers support it but that doesn't mean they will. In my area and experiences working in the IT field no internet company provides support for personally owned equipment. They only support and troubleshoot their own. This scenario you're expriencing is why; people think they may save some money not paying the rental fee for equipment but they run in to problems because the equipment they get isn't the best and when a problem arises they aren't sure what to do. If you use the provided equipment all troubleshooting, fixing, and liability to have a solid and reliable connection is on the provider. When we have our own equipment the service provider automatically blames our equipment and that's the end of their willingness to even talk about any issues with the service we're having. In my opinion the $5 or $10 rental fee is well worth having any issues or problems be the provider's problem to fix.
