Problem with my Linksys router

[FREDDY]

whenever i run a bandwith test thru the router i will get pathatic result lik max 1.36mpbs-3.49mbps but if i connect direct thru my modem i will get 12.49mbps

 

anyone can advise?

i am using a Wrt54G with 3 other computer at home in my net work only mine is wired the rest are wirless

[jB]

all 3 are using ne same time when you got this reading? lol if you connect via direct of course you'll get this much better hmm what plan did you subscribe to?

"Directly" as in via an Ethernet (deluxe-sized phone) wire, you mean?

 

That's because going wired somewhat offers higher throughput than that of wireless.

 

As to why there's this proportionate speed "gap" difference, it might be the media (wired/wireless), or the technology. If you're into this branch of computer engineering, ask the Internet Engineering task force (IEEE) peeps, or do some research. There's good reads on internet technologies on the web.

redbeacon, any idea why would it drop from 54mbps to his situation if thats the case ? because from what I know if many are sharing the same network then it'll be slower..right? or left?

[FREDDY]

i understand that if 3 com use at same time bandweith will be lower

but the result i quote above 1.36mpbs-3.49mbps lowest sometimes siao siao got 12.49mbps is on my own com which is wired and the rest are not using internet

It has been a long time since I attended Computer Networking class in school and my knowledge is a bit rusty.

So, for the benefit of you guys & curious me, I decided to do some research:

 

In order to reduce collisions and ensure that all connections get an even amount of bandwidth, TCP breaks all data into small packages before sending it along. Also, all data sent via TCP has to be confirmed before the next package is sent. These factors can certainly reduce transfer rates from the optimal 100 Mbps and will make them even lower with more activity on the network.

 

For our WiFi experimentation, we minimized this as much as possible by having a closed network with just the Access Point (aka "router" in PC shops/salesman lingo), wireless client and wired PC, but TCP/IP is no doubt still largely responsible for the lower-than-100-Mbps transfer rates we measured in our tests.

 

NOTE: Of course, you may be accessing the AP through a USB or PC Card on your notebook PC. USB 2.0 devices have 480 Mbps throughput, while PCMCIA can peak between 270 Mbps to over 1 Gbps (depending upon what mode it is in). So even if you are managing to get your data directly from the AP without going through a LAN, your adapter will still slow it down somewhat.

 

So dudes, these could be the bottlenecks that contribute to the drastic lower speed transfers:

 

[1] Living in the world of TCP/IP, this internet-working technology ensures data gets to the other side efficiently, safely and in one piece at the endpoint. Alas, for that to happen, PC's and other networking equipment have to engage in negotiation, packet-tization of data, and all the complex 2-end signaling for data transfers, and all that yadda-yadda checking. This causes data transfers to slow down.

 

[2] The usage of any USB 1.1 (not 2.0!!) networking equipment. Silly for one to do that actually, as its maximum rated speed is 12Mbps.

 

[3] Network Adaptor speeds set wrongly (rare cases)

 

[4] Computer slow; can't keep up, so data transfers are happening in a bit-by-bit fashion.

 

[5] Bandwidth "sharing" is biased - Each person only gets a slice of the whole pizza. Moreover, if your dog wants pizza, you can only afford to give him a small portion of it.

This analogy can also be said for multiple PCs connecting to one network equipment.

The latter case of the "dog"? Internet Connection Sharing is one of them.

 

[6] Too many "hops" to get to the internet destination (and vice-versa) - if you have too many networking things placed between a computer and a router that connects to the internet, [#5] applies and you get a natural bottleneck.

 

So Freddy, which abovementioned situations are you in now?

try DMZ to your com lor... or u can try upload tomato firmware n control the Mbps on wirless...

i understand that if 3 com use at same time bandweith will be lower

but the result i quote above 1.36mpbs-3.49mbps lowest sometimes siao siao got 12.49mbps is on my own com which is wired and the rest are not using internet

haha I get 5.5mbps when I'm in sch sometimes while my friends beside me get 54mbps

 

[2] The usage of any USB 1.1 (not 2.0!!) networking equipment. Silly for one to do that actually, as its maximum rated speed is 12Mbps.

woah this limit I didn't know.

yesterday i did a experiment, i connect to the internet by pass router ard 2000hrs i get a result of 20.59mbps then 2015hrs i tried again i got a 2.29mbps

 

BTW i am jus running on a 12mbps plan

[FREDDY]

so actually its proven that problem is not from my linksys router aready

i talk to starhub they say they will send a technician down to troubleshoot but i am wondering do i need to pay for this hahaha

lol no wonder you got just 12+ mbps

no service is free dude, even the govt shake leg also collect GST from us

hmm actually you can try resetting your router or settings then try connecting again w/out setting anything..see if it works, if it does then set your passwords and stuffs..if it doesn't, then pay them
