Gday, My setup: ADSL modem is a Billion BIPAC 711 (yeah I know, it's old, but it still works fine) connected by cable (it doesn't have wireless) to a D-Link DIR-615 Wireless N Router. My Internet connection is a 256/64 connection with TPG in Australia. The Billion's factory default IP address is 192.168.1.254, subnet mask 255.255.255.0 and the D-Link's factory default LAN IP address is 192.168.0.1, subnet mask 255.255.255.0. The D-Link has been allocated a WAN IP address of 192.168.1.248 (Default Gateway: 192.168.1.254, Primary DNS Server: 192.168.1.254, Secondary DNS Server: 0.0.0.0) Desktop PC is running Windows Vista Home Basic and is connected to the wireless router with a cable. Laptop is running Ubuntu 8.10 and Windows Vista Home Premium (dual boot, Ubuntu used 99% of the time) and is connected to the wireless router wirelessly. Both computers can access the Internet, albeit slowly, see "my problem" below. My problem: When connected directly to my Billion ADSL modem via a cable I can access the Internet at full speed all the time. When connected via the D-Link wireless router, either by cable or wirelessly, the Internet is very slow on both computers when surfing from page to page, however, if I run a speed test (eg http://www.speedtest.net/, http://www.ozspeedtest.com/bandwidth/) then I get full speed/bandwidth results. <u>NOTE</u>: There are no programs/viruses using all the bandwidth on either computer, they're only browsers surfing your average websites like Google, Sydney Morning Herald, online banking, computing.net, etc. I experience long delays whilst waiting to connect to these, and other, sites, and sometimes it just times out. Things I've tried: 1. Plugging desktop PC into different port on wireless router -- still slow. 2. Flashing router firmware -- no change to speeds. 3. Moving laptop around the house to see if distance changes the speed results -- still slow. 4. Have taken laptop to a friend's house who has a virtually identical setup except that he has a 1500/256 Internet connection. His IP addresses and wired/wireless/adsl/d-link setup are exactly the same as mine (different model D-Link), yet I get immediate responses from websites, no waiting or time-outs. 4. Returned wireless router to shop and received a replacement. 5. Calling TPG who advise that it's not them because I can do speed tests which show I'm getting my full bandwidth.

Your Billion unit is a modem/router combo. should be connecting to a Switch with a wireless accesspoint rather than to a second router's WAN port. I believe your problem lies in the fact you have two routers, each operating in different IP ranges, each with DHCP enabled. Simplest solution here would be to replace the billion unit with a Modem only. Goin' Fishin' (Some day)

@Richard59 Thanks for your reply, but I'm wondering what I might be able to try that isn't the "simplest solution"? I'd prefer not to have to buy more hardware but instead learn how to properly configure the hardware I have. I think I will learn more this way too. Thanks.

connect a wired pc to the billion combo. Do a tracert computing.net. Copy the results to a file connect the dlink router. Connect a wired pc to it. Do a tracert computing.net. Copy the results to a file. Now compare the results of the different captures. Where is the difference in time? Between or after the routers? Post both files here for our review. "Primary DNS Server: 192.168.1.254, Secondary DNS Server: 0.0.0.0)" Most likely this is your issue. You should call the isp and get their actual dns servers and list them here. You are telling name requests to "go out this door" and hopefully someone will answer vs go specifically here to this dns server Example of Oxymoron: Person who is pro life and anti sex education.

You have really high latancy times all the way thru which your router seems to be compounding. Here is an example of my tracert Tracing route to computing.net [74.55.15.34] over a maximum of 30 hops: 1 2 ms 1 ms 1 ms 192.168.1.1 2 15 ms 19 ms 10 ms 76.164.39.1 3 15 ms 14 ms 14 ms ge2-24-- Notice how my gateway is first? Yours is not listed. That indicates a problem to me with the router. The next ip is that of my dsl modem. Yet in both your tracerts the first ip to show appears to be the modem. The first ip should be your gateway of 192.168.0.1 if the dlink is hooked up correctly. You are connecting the billion to the wan port of the dlink router? It would appear from the tracert that this is not the case. If you are cabled correctly there might be a firewall on this dlink you should disable during this testing.
