Real world network speed question

Postposted on Thu Oct 13, 2011 5:54 pm

I've noticed that file transfers within my wireless network (ie from my laptop to my PC within the network) are only 1.1 MB/s and often dip to around 756kb/s. I have an AT&T wireless g Uverse router. Is this good? What sort of real world speeds should I be getting within the wireless network? I think theoretically I should be getting aroudn 6MB/s but am not sure.

You're not going to get very good speeds with that router. Theoretically, it can get to about 6MB/sec, but practically it's not going to be that good unless you're right next to the router, making it pointless.

What is so bad about at&ts uverse wifi router? And what should I do then?

No idea about pc to pc transfer, but the wifi router can keep 22mbps downloads easy, and that's with PSK2 or something.

With pc to pc transfers I resort to good old cable though. Two gigabit cards, one cord, and both HDDs have more than they can chew.

change the channel that its broadcasting on to the highest (which should be channel 11) and towards the bottom of that same screen there should be an advanced options, choose 400mw

Well can you guys test your home wifi networks and see what sort of transfer speeds you are getting from your laptop to your desktop and back and forth?

Just looking for a ballpark figure of what to expect from between 2 wireless g devices and a wireless g router

First off, remember that there are 8 bits in a byte. Every Windows or Mac operating system generally tells you that you are working in bytes, because that is the measurement used for storage (bits are used for bandwidth/speed/networks/etc.). So, on my old Wireless G router, I would max out at 56 megabits per second. This gave me a theoretical maximum of 7 megabytes per second. Now, you will never, ever get that speed. The reason being is that there is electrical interference, internal wiring within your house, electrical devices, etc. that are going to affect a signal. Its also going to be affected by distance. The further away you are, the weaker the signal. This can be off-set by setting up repeaters or what-not, and many people do. Your best bet will be to do what I did - when I needed to do a lot of large file transfers, I plugged it into a hard wire or I did it overnight.

The other thing I did was get a USB Flash Drive. That made things much simpler.

~22mbps real-world throughput if close to the access point. Gradually declining as distance or obstacles increase.

The reason my network transfers are important is due to some file synchronization requirements I have.

Is there anything I can do to improve my home wireless network performance?

802.11n with the right equipment, configuration, and distance limits can get near the 100mbps range.

The DLink 2553 is a monster that can act as an Access Point, Bridge, or Extender.

Plenty of options on the router side of the house as well.

I'd suggest you be quite careful depending on how exacting your speed needs are. Many factors influence wireless performance. Going wired helps control some of the variablility.

I'm going to echo everyone else and say go wired. Wireless is OK for Internet browsing and such, but if you are doing file transfers then wired makes so much more sense.

Practical throughput from a wired to wireless connection is going to be 22Mbps. However, 802.11 is half-duplex. This means that actual throuhput at the application layer will be impacted by the chattiness of the underlying protocol. Every time the recieving system communicates back, it will interrupt the incomming data stream and slow things down. This also means that a wireless to wireless transfer will have half the throughput of a wired to wireless connection. The sender transmits a packet to the AP, then the AP sends the packet to the reciever. While the AP is sending to the reciever, the sender cannot send another packet. This cuts practical bandwidth to around 11Mbps or about 1.125MBps, wireless to wireless. So, I'd say you are getting about what you should expect.

My experience is very bad with this router. I don’t think you will get what you want from it. I am also looking for some better option. I got so many suggestions, but I want the best one. Waiting to see what can be done in this situation. I am doing some study on different options, after that I will decide what to do. If you could find something better before me, do let me know.
