Network Speed

Hi,

Recently I figured that my LAN is quite slow. I think the reason is the access point I connected.

So I did some performance tests with the software "LAN Speed Test". My network consists of different switches and router some supported 100Mbit, some 1000 MBit. I think that's one issue that even devices connected to a 1000 router will connect using 100Mbit (at least Windows 7 says so).

Still I would expect a speed of 100Mbps but my measurement shows differently.

So my question is, if that's normal? Or is there an issue somewhere. I would expect to have a speed of like 80Mbps or something like that.

Pictures show speed measurements on different devices.

howdy, so as far as your network goes you can get UP to 100 mbps so sometimes with multiple online based applications running *(ie: skype, utorrent, ect) can clog your internet connection. As far as having a gigabit (1000 mbps) device connected to 100 mpbs device, your only going to get the 100. To achieve the 1000mpbs you need a CAT 6 cable, not CAT 5 and a gigabit based ethernet port in your computer. So your internet speed listed is normal. A god way of seeing how truely fast your internet speed is, go to http://www.speedtest.net/ and check that. There are some programs that help \this such as game booster which kills un-needed applications that clog up internet traffic.

also your router can play a big part to. If you have alot of devices accessing the network you'll want a dual band series router as they split up the signal to prevent congestion in the network.

hope this helps :D

Thanks for your answer. The tests above shows data within my local network. For the internet the speed is fine. But I expect a higher throughput in my local network.
You're also saying I should get 100mbps instead of 10, if I understood you correctly. Interesting is also that reading is much slower than writing. Does this make sense?

its not the device that is hindering the 1000Base,T its the port of that device. A device can have 100BaseT and 1000BaseT.
Also, you don't necessarily need Cat6. 1000BaseT was based to run on Cat5 cable. So youre fine on Cat5e. It can run on 1000BaseT network, but not on gigabit speed, still close. But, I doubt you will notice the difference. ( 5 to 10 bucks difference of a cat5 and cat6 cable, so no biggy)

yes, router can have a big role, but in this case No. Since you're doing lan test, router isn't necessary.

I assume you have d-link/vonage or other home (commercial) brand router. those are not "real" router. Routers used on homes/residential areas are router/switch 'hybrid'.

I don't know what you are trying to test here, you said your network consists routers and switches. Are you concern on the speed from pc-to-pc through only LAN, or through Internet.

ok im not going to write another article-ish paragraph concerning the speed on getting 80mbps or less at 100mpbs speed, so google, the Goodput and throughput on networking.

My concern is only the LAN speed. I think the devices (router and switches) are doing some bullshit with routing. But that's very hard to check, since I don't know how to access the routing tables.
I will try to remove the wireless access point. I have a feeling that it is slower, since I connected it to the network. I guess some devices have too much "intelligence" and disturb the network, even though they should simply broadcast/route the packages through the network.

I'm especially concerned at the reading speed which sucks a lot.
