Hi

Purchased one of these mainly because it has built in print server. Connection set up was very easy and I can surf ok but the connection speed is really slow, painfully slow. Checking the specs = Line Rate Upstream - 524Kbps, Line Rate Downstream - 176Kbps!!

I have uninstalled and reinstalled manually and via CD but the result is always about the same.

This however is not the entire story as this is the 2nd unit I have tried with exactly the same result. It surely has to be something I am doing.

Any ideas?

Thanks

WL 600G

Not good reading :(

And this from Dlink DSL - G604T

Maybe you could tell us more about the ADSL connection specs such as attenuation and S/N. Also do you have any idea about how far you are from your local exchange, obviously you wont know the actuall cable route but some idea would be good.

Other things of use are the wiring in your home, do you have filters on all phones, how many phones, faxs, sky boxs, etc. Do you have a monitored alarm.

Hi

I am about 5km from exchange but that is not the problem here as I can get anywhere from 1.5 - 2Mbps. I can live with that when I connect via my dlink but with this 2nd brand new WL - 600G connected I am only getting very poor speeds. When I had the first unit I rang asus directly and without hesitation as soon as I told him the Line Rate speeds he told me to take it back. I got another brand new replacement and I am getting exactly the same speed issue. I am using XP machine connecting via ethernet.

I can immediately plug back in Dlink and I am back to my normal speed of 1.5Mbps which I can live with. When I had the asus connected I have tried unplugging all phones (theres only 2), I have connected the modem to another jackpoint via vista laptop and I get the same poor speeds.

Hi, I am afraid that once you are over 4km its rapidly all down hill and DSL signals and the way various modems respond is very variable and unpredicable. The Asus is based around a Broadcom chipset which is normally very good on long lines but normally connects at a lower speed on long lines and is very stable once attained, the Dlink uses the AR7 which typically will sync at higher rates but loose sync and reconnect all the time.

In some countries (Telstra Aus for example) if your attenuation is over 56dB they will deny you service as it will be a service burden to them, yours is 63.5dB (worse).

My advise, move closer to the DSLAM, any service you are currently getting is simply good luck.

If you want to use the Asus to add wireless functionality to your Dlink then connect the Dlink to the Asus using a Lan port of the Asus not the Wan port (which should remain unused) you will need to turn the DHCP server off in the Asus and ideally migragte its lan admin address to the same range as the Dlink, you will be able to add wired connections to your network using the other 3 lan ports of the asus.

Hi,

Wow this is very interesting information - shame I didn't know this before I bought it. Oh well lesson learnt.

Your explanation does make sense as I would have doubt that 2 units would perform poorly due to a fault so my distance is probably the issue but I will take this up with the supplier and asus as this would have saved me a lot of time and cost if this was known prior. I have used 3 different modems at this house ever since I have had adsl which has been about 5 or 6 years now and taking into consideration my distance have never had any real problems.

Just to clarify, the Dlink is DSL - G604T (wireless 4 port) and the Asus is also wireless with print server and adsl2+. The main reason why I bought the asus is for the print server but the adsl2+ is bonus as according to www.telecom.co.nz/adsltwoplus I am due to be upgraded in approx April 2009. This being so does this mean I will have a DSLAM closer thereby the asus will perform better?

Also your suggestion for linking the asus and the dlink together still possible with both being wireless?

Thanks for your suggestions

Hi sorry I thought your Dlink was the 502 not the 604, so you already have wireless, so no advantage there, but you could link the two to increase coverage etc.

What is your rough location by town/suburb, its likely that you will be cabinetised on the date mentioned, this means that a DSLAM will be placed closer to you, hopefully within 2km, if so the Asus will be useful as the dlinks unless GenII dont do 2+ very well.

Hi,

I am in Nawton, Hamilton which is connected to the Te Rapa exchange. It is looking likely that I will be able to use the asus at that time so I will hold onto it and wait. The main reason for the asus was for the print server. This will allow me to print via laptop without having to turn on main pc.

Now what I intend to do is: adsl --> dlink --> asus --> main pc.

I will then connect printer to usb port on asus.

I am guessing now that I will need to turn off wireless on one of the units but not sure which one, or does it matter?

I really appreciate your replies, you've been a great help. You have beaten google!

Hi, there are 11 cabinets listed against Nawton in the Hamilton region to be installed. Two are listed for 1/4/09 that are FJN/01 and FJN/AJ, but there are 3 others for 1/7/09 being FJN/AM FJN/AP and FJN/P, then there are 5 for 1/1/09 being TRV/AL, AT, F, G and K. So if you know which of those you are currently wired by (now they are just cable joint cabinets but will be upgraded to carry a DSLAM).

Which you leave with the Wireless on is up to you, but you must ensure that you turn the DHCP off in the Asus, only have one DHCP server in a network or it goes wrong real quick, also it helps if you change the Asus address (which is probably 192.168.1.?) to the address range of the Dlink which will be 10.1.1.? but ensure its an address outside the Dlinks DHCP pool.

Cheers
Cyril

Hi

I have realised that I will need to have the asus wireless connected as I will need to be accessing the print server. Thanks for tips in regards to setting the 2 units together. Will be my project today (and probably tomorrow knowing my track record)

I dont know what I am connected to at the moment but I suppose it doesnt matter as it is not as if I can change it anyway so will just wait my turn.

Thanks again for your help.

Hi, you dont need the asus wireless on to access the print server. the eternet ports of both the dlink and asus and both wireless access points will be on one layer2 connection, so can be seen by all, but you will need to change the address of the asus.

I recommend you start by connecting you pc to a lan port of the asus (dont connect dlink yet) and get your pc to pickup an address from the asus, you will then be able to access the web config of the asus, and change first turn off the Asus dhcp server, and UPnP and then change the LAN IP address to 10.1.1.250 (all this is on page 38 of the asus manual), then save and reboot.

Now disconnect from the asus and connect via a lan port to the dlink, get your pc to get a ip address (you may need to tell your pc to repair the network connection to pickup a new address) once done you should be able to access the dlink on 10.1.1.1. go to the DHCP setttings (page 48 of manual) and set DHCP server ending IP address to 10.1.1.249. It then pays to save and reboot, see tools/system (page 90 of manual) otherwise the dlink has a habit of not saving settings properly.

Once all done you can connect the two together via lan ports and you can now access the asus on 10.1.1.250, you now have a static
IP address area 10.1.1.251-254 for a server or other device you want static. You will now want to config the wireless setup of both, which you use is up to you, or you can use both but ensure you use two different channels that are 6ch appart (ie 1,7,13) to prevent interference, if you give them both the same SSID then PCs should seamlessly shift between them.

Great instructions. I got it working exactly how you have outlined.

Got printer installed as per manual and can print fine from main pc but have to work out how to do so from laptops when main pc is switched off.

Thanks Cyril for all your help. You definitely deserve your Trusted tag.

Thanks
Sam
