Thread: Network Setup problem #4,547,865,042

When I transfer files from my main PC to my laptop it takes bloody ages, so I assume the router is incorrectly configured and it may well be sending the file via the server or some other such nonsense.

I have a single port, standard ADSL modem which takes the data line from the exchange. Then is the D-Link Router; one port is connected to my PC and then wireless to my laptop.

If someone has the patience to ask for the relevant screen shots, I may have a change of utilising the high-speedyness of this thing and stream vids straight from my PC to the laptop.

Otherwise, I guess I'll have to do it the old fashioned way using a flash drive.

But, I'm not even getting the lower speed of my wireless card in the laptop. It's about the same speed as my internet.

low WIFI reception ?

the best way is to connect your laptop through the LAN port (RJ45) on the router and do the big transfer then. Will need to setup a multi-homing IP address so you don't give the same IP for 2 different adapters on the laptop

What do you get running speedtest.net on the wired and wireless PCs?

If you're seeing a strong Wifi signal on the laptop, it could be interference.

You could try setting a different channel in the router, and reconnecting.

Oh and get the IP address of the laptop and on the wired PC, open a command prompt and

tracert xxx.xxx.xxx.xxx

I am the biggest dummy you know marmers and have come to you for help. But I have D link as well and got much lower speeds via wifi to my computer that hooks to the new HiDef TV. So I had them come look.. Had to wait a couple of days and so had a look I have three ports in my Dink as well. Why not disable wifi, hook to lan and get the files that way. Dont give me too much shit mate. I did get the sound to come out when we watch via compuer and HiDef when it would not work with HDMI cables. I am sure its not right, but it works. But this it True admitting it, not whoever you have. I finally have a straight up technician here. Wow.

a screen shot of the LAN settings of your ADSL and your Dlink might be somewhere to start - we can look to see if there are config issues that conflict

and the ipv4 setups of your 2 computers - IP , subnet , gateway or are they on auto DHCP ?

Sorry for the delay - bin bizzy.

OK - The laptop is in a different room, so I don;t want cables all over the house. The signal strength is 100% superbio.

Fully auto on both computers.

And the results from browsing Speedtest.net - The Global Broadband Speed Test to your local ISP on both computers?

Your wifi connected laptop and your PC will connect to each other through the D-Link router and that data is not going somewhere else.
Your Huawei modem won't see it, wont get it, it is local to the D-Link.

What transfer speeds do you see? (Divide file size with transfer time in seconds).

Filesize - 60,942kb
Discovering Items - 50secs
Copying Items - 2mins 50secs

Where did this Huawei come from? It wasn't in the OP. I'd certainly make sure both connections go to the same router.

That is 3MBit/s, compared to the theoretical max of ~20MBit/s for your wifi connection.
The 50 sec for discovery tells me that this is a copy of many hundred small files (maybe thousands?) and that will reduce your transfer rate drastically because your OS has to spend time creating each file in the directory structure on the receiving computer.
Check what result you get when copying one huge file!

He has already said that the PC is connected to the D-Link, right?
Can you see any wireless config tab in his screenshot of the Huawei gui?
Forget about the Huawei modem, it is not involved in this file copy..

make sure that you have one subnet, not 2, you can choose 0 for the 192.168 class

that is your laptop and PC should be on the 192.168.0.x LAN, that will avoid your router trying to poorly "route" communication between the two subnet

yes, it seems to be the source of the problem, the routing between 2 local subnet

this seems to have been setup by a dumb Thai, shame on Mtd for not knowing better

both it seems,

You need the "TCP/IP 101 for dummies" crash course Butters..
Both his PC's are in the same subnet, under the same D-Link router, so a low throughput between them has nothing to do with his main WAN modem/router being in another subnet.
The configuration Marmers has can at most cause him port forwarding problems with traffic coming in from the internet.

I have btw the same type of double NAT/double subnets for my guest network here and it works without problems, theoretically it should and practically it does.
My reason for it is to have guests on a separate subnets so they have no chance to access computers on my subnet.

ok, and that makes sense, but that's not the case here, he wants the PCs in the 2 "LANs" to communicate together

I suspect there is "routing" between the two local subnet and it's cause for the poor performance by a low-cost switch, poor software or poor processing speed of the route table. Would they use some kind of "MAC Caching" for the 2 subnets ? I have tried setup such route between two local LAN with one of those very low cost switch and performance was also very lame, even though it was for more than just 2 PCs.

I am sure with the right equipments, this wouldn't be even an issue.

I used to be a Network Administrator so no need for the "dummies series" but thanks for the recommendation of your personal readings

hehehe, I hear you

Hmmm. Aurora doesn't show any screenshots in this thread.

I spend my time trying to stop them creating them.

I would rather he confirmed that he had the Huawei LAN plugged to the WAN on the dlink - there is a good chance the dlink is not a router

he may have the huawei LAN plugged to the dlink LAN

I just adjust my routing table to circumvent the damage
