Can I use LAN (with proxy settings) and wireless connection (without proxy settings) at the same time?

I'm using a laptop at work connected to company's network (with firewall and proxy enabled).  I cannot go onto sites such as gmail, mail.yahoo, etc.  But, there is also an availble DSL wireless connection that I can connect to (no proxy/firewall), which I cannot access company's intranet.

If I was want to switch from company LAN to wireless connection, I have to disable the LAN connection, enable the wireless, remove the proxy settings in internet browser, but I won't have access to the compay's intranet/email when I'm on the wireless.

Is there any way I can use the wireless connection and company LAN at the same time?  Maybe have a different browser such as Firefox use the wireless connection, and the rest of the applications/IE brower use the LAN.  Is this possible?

Any help would be appreciated!

i dont' think so that you have to disable you ethernet connector.
Have you specified the gateway on your ethernet adpater,if yes then remove it & don't specify any gateway on it, as you are using proxy when you are on ethernet adapater.
And when you are connecting to wireless i suppose you must be specifying gateway in that.
Then just diable your proxy setting from your IE & you can surf net as well as connected to your office network also.

I'm not 100% clear about your recommendation, but we use DHCP for both ethernet and wireless.

GizmoKidCommented:
the ip which you are getting from DHCP on ethernet adapter set that IP only as static on your ethernet adpater without gateway.

Another way of doing it is,go in Network Connections on top MENU there is a Advanced ----> Advanced Settings----> Adapter & Binding.
Set your wireless adapter on TOP means first priority then your ethernet adapter.
It will work.

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

What happens if you do everything but disable the LAN connection?

Sorry if I wasn't clear in my question, but to clarify, I would like to NOT keep changing my proxy setting back and forth.

Is there a way to keep one proxy setting for the LAN for certain applications (e.g., IE, Lotus Notes), and disable proxy settings for another application (e.g., Firefox) using Wireless?  And...keep these applications running at the same time?

Also, I'm using Windows 2000.

GizmoKidCommented:
Ok , You can do that, don't diable your proxy setting in your IE & don't add any proxy setting in Your Firefox.

You can do that way also, when you user IE its traffic will go through your ethernet adapter & when you user firefox its traffic will go through wireless adapter.

I understand that - that's why I asked my question.

GizmoKid,

Upon your recommendation, I went into Network Connections on top MENU to Advanced ----> Advanced Settings----> Adapter & Binding, and set my wireless adapter on TOP for first priority then the ethernet adapter.

Then, I configured IE to work WITH the company's LAN proxy (which goes through firewall), and I configured Firefox WITHOUT a proxy (hoping that it'll go through wireless).

It doesn't work.  When I use Firefox to connect to the internet, it comes back with timed out response.  Only when I configure FireFox with proxy will it let me connect to the internet.

Please advise.

If I disable the LAN connection, and connected to wireless without proxy settings, I'm surfing the web.

Was that your question?

Did you try the gateway thing which i have asked, remove the gateway from ethernet adapter,set the ip which you got from DHCP as satic without gateway.

Then try. i have tested this on my desktop which have two adapter.

I have also install the firefox browser & things works at my end, i hope it will work at your end also. Please let me know.

Nope, it won't work.

When I leave out the gateway, it doesn't let me connect to the internet.  Help!

GizmoKidCommented:
You are leaving gateway only in your ethernet adapter & not in your wireless right.

I am leaving NOT putting in gateway for the ethernet.

Wireless is DHCP.

Might I suggest we directly address what now clearly appears to be a routing issue?

Start->Run... cmd (or "command" if you have old windows)

netstat -nr

Do that when it works, and when it doesn't (and post the results here, if possible - you can and should mangle the IPs (although consistently)) - the answer should then become clear.

Cheers,

GizmoKidCommented:
First check from your command prompt that are you able to resolve DNS or not
ping www.google.com

If not then check whether you have defined DNS on your ethernet or not.

once you get the IP of google.com then run traceroute command
tracert 66.102.7.147

& see from which IP your packets are going out (It shuld be your wireless IP), because there is no gateway defined on your ethernet thats why windows itself take wireless adapter gateway to route the traffic.

I'll try that Monday, since I don't have access to the computer on the weekends.

I'll post my response first thing Monday.

The--CaptainCommented:
Cool - if you can provide the results of "ipconfig /all" and "netstat -nr" when connected to the LAN, and when connected to the internet, the problem should be evident.

I couldn't test this because for some reason my wireless isn't working today.  I'll try it again tomorrow.

But a quick question: Do I need to "hard configure" my DNS server for the ethernet connection as well along with IP and subnet mask?

Also, when I'm on DHCP, and check out my ipconfig /all, I also see WINS configuration.  Do I need to "hard configure" my WINS as well?
0
 
fatogreAuthor Commented:
Nope it doesn't work quite as planned.  Here is my current setup:

Ethernet: Static IP, Static Subnet Mask, Static DNS Server, Static WINS.  No Gateway

Wireless: DHCP

When I configure it as above.  I can use the wireless to surf the web, but I cannot get into the inTRAnet sites (even with the proxy on).  It defaults to the wireless each time.

Broadcom NetXtreme Gigabit Ethernet is the "ethernet";
WAN (PPP/SLIP) Interface is the "wireless".

Ok,
Change the Pripority of your Wireless adapter to 2nd.
Which i think is still on top in Adapters & binding.

& what is your proxy IP Address? which you are using
0
 
fatogreAuthor Commented:
Sorry, it still doesn't work.

The proxy is not an ip address, but the server name.  Should I put in the ip instead?

I'm beginning to lose hope....but thanks for your responses.  I'm increasing the point value!

GizmoKidCommented:
ok,
I suupose the proxy which you are giving in IE is in your internal subnet only.
Because we have deleted the gateway so only internal proxy will work,
And yes you have to give IP address only not name of the server, as i have seen that you have external DNS defined at your ethernet.

fatogreAuthor Commented:
Here is what I know:

Ethernet will not work without a gateway specified, even with the wireless on.

Yes, proxy is an INternal proxy.  I've tried to change it to the ip address and it still doesn't work.

The DNS defined on my ethernet is INternal not an EXternal DNS.

GizmoKidCommented:
Ok,
Tel me what  Gateway IP You got on your ethernet when you set it on DHCP.

We will define route for that, then your problem will be solved

How will you define a route?

Go to Command Prompt

then write this command

then tell me the result

GizmoKid,

It works!  Before I give you 400 points, can you please explain the "why/how"?

Why/how is it that if I leave out the "gateway ip" for LAN, it routes to the Wireless?

What does "route add 10.0.0.0 mask 255.0.0.0 xxx.xxx.xxx.xxx(gateway IP of your ethernet)" do?  How does that route to wireless?

Thanks,
Kenny

GizmoKidCommented:
this command will add a static route for 10.0.0.0 subnet, all local traffic will be directed through your ethernet & rest will go through wireless, as only on wireless gateway is defined.

To See all routes on your system type this command on your command prompt.

c:\>route print

GizmoKid,

Is it possible to do this without your solution's one of the following?
1) Static IP - is it possible to use DHCP?; or
2) Removing gateway - is it possible to leave in the gateway?

With the current solution, my laptop doesn't boot up correctly in my company's LAN.  I have to change it back to DHCP and bootup again.

Thanks,
Kenny
