ROUTER AS A SWITCH WITHOUT NETWORK PING ISSUES

[DBG]

ok so i had connected 2 pcs (using cat 6e and cat 5e cables) to a really old router without a net connection and when i startup rainbow six seige lan server the one with a cat 6e cable has 80 ping and the other one is around 80 

is it because of the old router not being fast enough or the cables or something entirely different 

and i was planning for an outdoor lan party so will adding 2 more pcs increase the ping even more? 

sorry for my terrible english and networking knowledge

It will be fine it's an older router it has a limited bandwidth 

Spoiler

I think

Just to be clear - both computers were connected to LAN ports of an old router, and you were only using it for LAN gaming? Did you make sure that the computers were using that wired connection, and weren't instead communicating over a shared wireless connection (easy way to test is to turn off the wireless on them)? If a Windows computer has two networks, one that provides internet and one that doesn't, the one that povides internet is usually used by default for everything unless it is forced to use the other (for example, by specifically addressing the other computer using the IP address of the non-internet connection).

 

If both computers are connected directly to switched LAN ports of a router, the latency of small packets should be roughly:

10Mb/s: 20ms

100Mb/s: 2ms

1Gb/s: 0.2ms

 

(Based on a 50 bit packet, Store-and-Forward switching, 4 hops [computer A to router, router to computer B, computer B to router, router to computer A], and assuming that switching in the router, processing in computer B, and all wire transfers take 0 time. In the real world I would expect results up to three times as long)

 

So if the router only has 10Mb/s ports, the 80ms in-game latency actually sounds reasonable, depending on the game architecture. If the router has 100Mb/s or faster ports, then 80ms doesn't make sense.

i am really sorry but i understood very little of what you said

the router i have is dlink dir 615 please can u tell me if it is good enough 

but the computers were for sure connected via lan ports only 

and if i connect a network switch to this router will it speed it up ?
the cheapest switch i found was TP-Link 8-Port 10 / 100Mbps Desktop Switch (TL-SF1008D)

and in addition to all this in games like l4d2 and cs 1.6 the pings ranged from 5-20 max

That router has 100Mb/s ports, so buying a switch would not be any improvement unless you buy a gigabit switch.

 

There are a few things you can do to try and improve the situation:

• Turn off the wireless on both computer, if they have any, to make sure they are connecting to each other over the wired connection
• In the Adaptor settings in the Network and Sharing Center, set both of the computer's ethernet port to "100 Full Duplex"

so is the switch good enough??

and will inform you soon about the impact on performance with the settings change 

thanks a lot

The swith is no better than your router. It will make no difference. It will be a waste of money to buy.

can u suggest any other switch and will it even reduce the ping?

Buy any Gigabit switch. In theory it will reduce the ping, but I do not guarantee it, and it won't reduce it by much (less than a 2ms difference). And the same thing about making sure the computers use the wired connection, and not wireless, still would affect you. But if you bought a gigabit switch, you would not want your ports set to "100 full Duplex", you would want them set to Auto or to Gigabit. Also the gigabit switch will only help if your computers have gigabit ethernet ports.

you are getting 80ms ping to a server on you lan when both server and client are connected to the same router?

 

that is oddly high.

ok so the 100 mbps full duplex did lower the ping to 60 and 50 

thanks a lot for the info

will let u know about the difference it makes with a gigabit switch

thanksss a lot

and can u suggest any good offline lan games to play with atleast 4 ppl(in total) ?
