ethernet adapter conflicts with WLAN connectivity

greetings, i'm trying to sort out a problem. here's my setup: i have two routers, one is a VDSL router with wireless functions, which i'm using to connect to the internet, and the other one is a tabby router i'm trying to use to connect my laptop, PS3 and desktop computer. i've set the VDSL router to use the 192.168.1.* domain, and the other one uses 195.165.5.* (both with netmask, which connects the hardware in my room through ethernet cables (they're the right ones, please refrain from pointing out that i should use non-crossover cables because i already know and am already doing so).
now, here's the problem: somehow the laptop works, and the PS3 can't use the wireless card and ethernet adapter simultaneously anyway, but when ethernet is enabled on the desktop, its wi-fi connection goes off; it can reach the internal network, but somehow it can't ping anywhere past home. i tried a few things, and it appears that the part causing conflicts is the IP address protocol on the computer's ethernet card; i've tried most things, set a manual IP, let DHCP assign one automatically, even changed around the netbios settings but all to no avail. could anyone provide some useful insight about what might be going wrong here? thanks in advance for your reply.

Yes, how would you decide on...

Which DNS to use and more? It doesn't sound like a valid configuration.

on the WLAN both the DNS and gateway are always mapped to, which works well. that leaves the ethernet adapter, for which i tried several things: i both tried mapping it to and leaving it blank, but again to no avail. DHCP doesn't pass it the right parameters either, so i have no idea what to try next.

Never heard of mapping.

In reply to: Re: Yes, how would you decide on...

No class or book ever called setting the settings "mapping." What text book are you working from?

Also, the basic numbers you provided look incorrect, invalid. Let's be clear here. I don't teach basics. I will point out such is invalid and if there is a one to three line answer I give it but in this case you are trying something invalid that should not work as you have it.

Give it time for you to read more about TCPIP, routing, and how it works. For now, use one or the other connection.

not the point

In reply to: Never heard of mapping.

i'm already aware of the fact that i'm doing something wrong, that's why i'm asking. i'm not going by any book, i usually try to sort things out as i go but i find it normal to ask someone's opinion when they don't work, because long story short, streaming data to a console is simply not worth going through an entire theory book. now, since my purpose is to use both connections simultaneously switching from one to the other is out of the question (i want to make my network more versatile, after all), so if those numbers really look invalid could you please just point out what's wrong with them, or better yet suggest a possibly working IP to use? thanks.

I see a problem.

In reply to: not the point

You're trying to solve a problem but rather than share the problem that needs to be solved you skipping ahead to a very expert deep knowledge area of TCPIP and more.

If you just wanted to let your PS3 connect to the internet via your wired laptop over the laptop's wifi card then I could point you to ICS and articles about ICS.

Then again there are some that want to do something without learning the underlying knowledge required. How would you respond to those?

i would respond that none of that matters to me, that you're not helping any and that in the future i shall turn elsewhere to ask a simple question rather than arguing with someone who is obviously more interested in spouting out wry comments about people's lack of expertise rather than giving a hand to those who know less. incidentally, none of what you said points to the fact that you know anything at all about networking: for all i know you could just be trolling and not have a clue about what needs to be done, but i don't care. i only need a simple fix, and since apparently this can't be obtained here i'll take my business elsewhere. thanks for nothing.

You're welcome.

In reply to: Re: I see a problem.

I had hopes that you could share exactly what you needed to do rather than explore something very technical and likely the wrong solution.

Instead I've offended you and wish you the best.

setup question

In reply to: ethernet adapter conflicts with WLAN connectivity

I'm understanding you want to connect the second router to the DSL router? Are you looking to use the additional ports of the nonDSL router to connect other devices and have it reach the Internet?
