SWITCH higher latency

[JOLO14]

Hello

I have a little question. My current situation is: I have ADSL modem router netgear N250, from it i have RJ45 to my computer. Now i need to conect 2 computers. Solution is SWITCH. From router to SWITCH with RJ45 and from SWITCH to my 2 computers with RJ45.

Question is: since i play games such as LOL and CSGO (semi-pro), i need stabile internet connection and LOWEST ping posible. Now i have ping around 35 ms. Will adding SWITCH increase my ping (latency) ?

Thanks for answers

Slightly, probably not noticeable in tests.

I should add that the majority of latency is going to come from all the hops your data travels to get to the server and back. Each router and switch and repeater add latency on the trip.

If I recall from my electronics days, and this is surely out of date, that the average latency added by a digital gate was 10ns.

With a ping of 35ms your one way traffic is taking 1.75 million time longer then 10ns. Even assuming your new switch added 100 gates it would just account for 1/1000 of a ms.

That and the speed of light account for your latency.

Hello

I decide i want to have also wifi connection so i want to buy wifi router instead of switch. They should do the same work but router can also provide wifi conection not only wire. But what is faster? Router or switch. Again i want to have lowest ping posible. If the router would cause higher ping than switch i would juts buy switch.

Are you talking about bridging two wireless networks with a physical cable?

Or having physical cables on each end of two routers and bridging the routers wirelessly?

Not really clear from your description what you want to do.

That excerpt from the how to is correct. You can't have two routers on the same network running DHCP. But it seems to have left out everything else to get a sense of the goal.

Modem - ISP -> local network (usually from the ISP as a modem/router)

Router - Smart network switch that is programmable/configurable. You can block ports, set encryption, deny access via MAC, and so on. Basically it figures out where something needs to go by the information in the packet and comes up with the most efficient way to get it there.

Switch - A better network device, the switch reads the to and from and sends it where it needs to go. Since traffic isn't being broadcast, you get full speed to every port.

Hub - a very basic network device, basically sends all data from an incoming line to all outgoing lines. Quite wasteful in that you divide bandwidth between everyone.

I feel like a post was deleted at some point... oh well, best for that one to be in a new thread.

There are trade-offs, but you will not notice the performance difference between a switch and a router at the consumer level. Only artificial benchmarks would be able to tell a difference.

For a simple connection the switch is preferable. For multi-user/multi-device a router is preferable. I

n the home the biggest increase in latency you can get is using a wireless connection, since only one device can broadcast at a time on any given channel, each device actually waits on the others. So as soon as you have more than one it starts getting worse. (And it isn't just your devices, anyone else on the channel/frequency has the same effect, even if they aren't on your network)

Your connection to games is still through your ISP and you are going through at least a dozen routers that you have no control over to get to any website.

Run tracert www.google.com from a command prompt (or substitute the IP address of the game server in question) and you can see what I am talking about.

Sorry if i didnt describe it better, my english is "small" . So i tried to draw it. Hope u will understand better.

Tried to add link as picture but it didnt work so here is link :

PS: i tried to google a bit and this is what i find, if anyone could confirm it .

If your wireless router is not going to be the main firewall for your network then you can do the following:

Configure the wireless router with a static IP address. So if your home network is 192.168.1.X give the router a static IP along the lines of 192.168.1.250 (making sure that no other device on your network has the same IP address)
Turn DHCP off on the wireless router
Configure the SSID and security settings you want for your wireless connection
Plug the cable that you were using for your laptop into one of the LAN ports on the router
At this point your laptop should see the wireless router and you should be able to connect to it using the credentials you specified in step 3 and have internet access.

There isn't enough information in that excerpt to say. Seems like it is towards the end of the information. Do you have the link to all of it?

You are wanting to bridge two routers with a network cable. Though I'm not entirely sure why you need to do that.

If you have no devices connecting to the first router you could use a long cable between the filter and your singular router.

If you want to stick with the original plan here is a guide:

i paste same text twice, my internet froze and send sequest twice. Deleted

 

[Eximo]

You keep pasting the same bit of text, it looks like the end of some configuration but where is the start? It references a step 3, there are no other steps mentioned.

Not sure what fears you have. What you are asking for is relatively common, but isn't exactly simple to set up.

DSL Filter -> Modem/Router --LAN-- Router -> Several devices. My point being that if you have no devices on the first router, than move that router to be near the majority of devices. What you are proposing requires a long cable either way, you just picking where you want to do it.

If you do have devices using that first router, than your idea is fine. You just need to bridge the two routers. You can have separate WiFi setups at each end, or if you can configure one of the routers as a repeater, then everything can share the same WiFi network.

Oh now i see what u mean. I paste this from another site but numbering didnt paste. Fixed

1. Configure the wireless router with a static IP address. So if your home network is 192.168.1.X give the router a static IP along the lines of 192.168.1.250 (making sure that no other device on your network has the same IP address)
2. Turn DHCP off on the wireless router
3. Configure the SSID and security settings you want for your wireless connection
4 .Plug the cable that you were using for your laptop into one of the LAN ports on the router
5. At this point your laptop should see the wireless router and you should be able to connect to it using the credentials you specified in step 3 and have internet access.

In your link, what is my case? LAN to LAN or LAN to WAN. I dont need to see other devices connected to my "first" wifi router or i dont need some parent monitor internet access. So i think my case is LAN to LAN.

PS: this is the router i want to use D-Link DIR-600. I was a bit surprised about price, its the same price as SWITCH i wanted to buy earlier - Zyxel GS-105B v3 . Though router will be more expensive than switch..

I think what you are proposing is LAN to LAN between a pair of routers.

The actual end configuration is up to you. Just have to follow a few rules. One of the routers has to have DHCP off. The wireless can be on or off on either end. If you want to bridge the wireless networks, the devices will have to be somewhat similar in terms of encryption and frequencies. I'm not 100% certain a static IP is necessary, generally your master router will be sitting a the first IP, usually 192.168.0.1 and dole out IPs to everything else. With the second router having DHCP off it will receive an IP from the master.

Those instructions you posted seem to assume only one router has wireless capability. Not really sure what Step 4 is about, seems like some steps are still missing as nowhere does it mention plugging the laptop in to anything.

RE PS: You would think that, but you have the odd case that there is a much greater demand for routers vs switches so there is more competition that drives the price down.

OK, thanks for answer. Just to be sure, like if i would use normal switch, ping difference will be almost unmeasurable even when i use wifi router instead of switch?

In some instances a router will be faster than a switch, but usually the simplicity of a switch will be better. The speed of your internal network is not a limiting factor when accessing the internet or moving files around. That comes down to bandwidth and the distance to the system you are connecting to. In your local network you should not see pings greater than 1ms, and these are rounded up significantly.

Thank you very much for your time and answers.
