Dual nic's, dual networks, setting this up? [SOLVED]

Hi,
I have a laptop with wireless (rt2500) and wired nic. Both work fine, but I am in a situation where I need to connect the wireless to one network, and the wired to another network. (Wireless to the internet, and wired to small home network). Im not trying to bridge them. I can set this up pretty easily, just using DHCP for both the wireless and wired, but after 15 minutes to an hour, requests I make on the wireless side try going over the wired network.
I tried fix it by:
route add -net 10.18.0.0 netmask 255.255.0.0 ra0
route add -net 192.168.1.0 netmask 255.255.255.0 eth0
but still after a half hour or so the requests I make on wireless (internet) try going over the wired interface.
Any ideas on how to keep these two interfaces associated with their respective networks?
Thanks

I just had an AHA moment and think I solved my problem.
route -n gives me
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
10.18.0.0 0.0.0.0 255.255.0.0 U 0 0 0 ra0
0.0.0.0 192.168.1.1 0.0.0.0 UG 0 0 0 eth0
0.0.0.0 10.18.0.1 0.0.0.0 UG 0 0 0 ra0
So both eth0 and ra0 have destinations to the 0.0.0.0 network. Thats no good because only ra0 really goes to the internet. so I just did
route del -net 0.0.0.0 eth0
So now
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
10.18.0.0 0.0.0.0 255.255.0.0 U 0 0 0 ra0
0.0.0.0 10.18.0.1 0.0.0.0 UG 0 0 0 ra0
Only one route for the internet, no more problems

Dual Networks? Is this right?

hello, all - i'm sure this topic is out there, i just can't find it, so here goes...
i have an airport EXTREME base station (n) and TWO airport EXPRESS base stations. according to everything i've heard and read, the network will work only as fast as the slowest connection. which means i won't get N speeds, but only G speeds, as the EXPRESS moves at G only. which also means if i breakdown and buy an apple TV, it won't take advantage of the N speed of my new router.
HOWEVER, i believe i read or heard that i could, essentially, set up TWO networks - one with the AEBS and the other using the EXPRESS. that way, i'd be serving N speeds to the TV, and G speeds to my computers (G5, mac mini (core duo only) and powerbook - all of which, by the way, can only obtain G speeds). is this true?
if so, here's what i did - i setup the AEBS (connected to my cable modem) using WDS (at n speed, b/g compatible) as a WDS main, and connected the EXPRESS (as a WDS remote, both on the same channel) to the AEBS via ethernet. it APPEARS i have two networks now under the airport menu in the finder.which, if i've done this right, means i can connect my computers the G network and, when i get the TV, connect that ot my N network. is this at all right, or even close?
i've read the manuals and searched the chats, but seem to be lost on this one. ANY help, advice, direction is CERTAINLY appreciated.
THANKS, oh wonderful mac gurus.

It is true that the overall bandwidth of the 802.11n network will take a performance "hit" when non "n" devices are connected to it, but not all the way down to 802.11b/g.
HOWEVER, i believe i read or heard that i could, essentially, set up TWO networks - one with the AEBS and the other using the EXPRESS. that way, i'd be serving N speeds to the TV, and G speeds to my computers (G5, mac mini (core duo only) and powerbook - all of which, by the way, can only obtain G speeds). is this true?
Yes. It is called a "dual-band" network and setting it up is described in the Designing AirPort Networks Using the AirPort Utility document, starting on page 48.
if so, here's what i did - i setup the AEBS (connected to my cable modem) using WDS (at n speed, b/g compatible) as a WDS main, and connected the EXPRESS (as a WDS remote, both on the same channel) to the AEBS via ethernet.
A WDS is NOT what you would want in this scenario, instead you would want to set up a "dual-band" network as described in the link provided above.

I have a Apple Power Mac G5 Dual 2.3 GHz/6GB RAM/500GB HDD/Superdrive PowerPC Desktop and just bought an Airport Extreme card for it. The card is recognized but will not see the in-house network. This is a pre-intel computer. Do I need an antennae?

This is a pre-intel computer. Do I need an additional antennae? If so, which one because my research is confusing me about what is supposed to work with this computer.

Please check out the following Apple Support article to see if your particular Power Mac model supports an external Wi-Fi antenna.

Need to set up a dual network with AEBS"n" and AEBS"g"

I've got a new Airport Extreme Base Station 5GHz (n only) wireless network set up for my new Apple TV.
But now my older Macs can't access the wireless network. So I'd like to set up my old AEBS"g" in order to connect.
I tried plugging the ethernet between the two AEBS and configuring them. I got a message saying the WAN wasn't plugged in. I thought I needed to use the LAN.
I'm really confused. Any help would be appreciated. Thanks!
-Mike

IMO, page 41 on the "Designing AirPort Networks" is incorrect. On the TC or AEBS that's set as a bridge, the WAN port should be set as Ethernet (not PPPoE), and the Ethernet uplink cable should go to the WAN port. If not, you will see the "WAN wasn't plugged in" message.

Dual network problem - trouble seeing B/G network in farthest location

My iPhone and MacBook Pro cannot see the B/G network in the room farthest from the main base station, even though there is an AEX in the room set up to provide internet and Airtunes.
My set up is:
N network - 2 AEBSn base stations
B/G network - 1 AEBS (connected by ethernet to the main AEBSn) and 3 AEX's
I tried to follow the directions for setting up a dual network and think I have done it correctly. But even though I receive a strong N-network signal in the farthest room, I cannot see the B/G network at all, it just seems to disappear.
Any help would be most appreciated.

Thanks HPM2.
I guess third times a charm. The hard reset of the AEBS finally worked and Airport Utility recognized it and I set it up to join my existing network as a WDS remote.
It works well, but every time I try to access the newly added AEBS b/g via Airport Utility, I get asked for my keychain access and then for the AEBS b/g password. I established the AEBS password during the Airport Utility setup, but now it is not recognized and is not even in my Keychain Access Utility. I selected the "remember keychain" checkbox during the set up too.
Any ideas on this keychain issue?
Thanks again,

Nokia 701 Restarts when it is in Dual Network Mode

Hi,
I owned a 701 since Dec'11, but recently after the latest sw update after some day s it started restarting on its own almost 10 -15 times a day. I able to drill down the root cause after some un-installation and setting changes, It only restarts when its on dual network mode when it tries to switch between 2G to 3G and vice versa.
Any one has observe this issue & any solution.
Currently I'm using Airtel network in INDIA.
For temporary if using either 2G or 3G according to my need due to the issue.
Thanks,
Amit.

i have run memtest for 11 h, no errors. I have tried to higer the volt but it dosen't have anny effect but once i put the vikt to 1.8 and it worked but then the computer got ustable

Re: Want to add TC to wireless network but need dual network setup

Currently, have an older AEBS (b/g) connected to my modem. My G5 is connected to it via an ethernet cable. My Intel iMac is connected wirelessly to the AEBS via an older (b/g) AX which amplifies my signal and is also connected to a stereo system). I have a 1 TB TC and would like to set up a dual network so that I can capitalize on the faster N speeds offered by the TC and backup both computers.
Modem -> TC -> AEBS -> G5 (by ethernet cable): the b/g network
TC ->Intel iMac (wireless): the n network.
Will the older (b/g) AX work with iTunes on both computers? Which network should it be a part of?
And how does this dual network configuration work for backing up both computers? Anyone have something similar? Will Airport Utility do this or do I need to do it manually?

Thanks for pointing out that my AEBS needs to be in Bridge mode and for clarifying that AirTunes will work on either network.
Any experience with using TC as a backup on a dual network?
I wonder how many out there have taken advantage of third party apps that given one more options for backing up less frequently than TC does?
Thanks again for posting.

Lackluster Dual Network Setup - HELP!

Here's my setup:
DSL
I
I
AXBS (UFO) 2.4Ghz b/g --> PowerBook G4 (10.4.11); iPhone (Original)
I
I
Time Capsule 5Ghz n (Bridged) --> MacBook Pro (10.5.4); MacBook (10.4.11 - n enabled)
The Time Capsule's Strength and Range is suppose to far exceed that of the older Base Station. When I'm near the location of the two transmitters the 5Ghz n is barely twice as fast as the 2.4Ghz b/g (tested with large file transfers between the 2 newer laptops, and then file transfers between the MacBook Pro and the older Powerbook). When I'm farther away the 5Ghz n drops away and the 2.4Ghz b/g remains relatively strong. Switching between the two networks when I'm at a distance strangely still shows full solid bars for both networks.
So does anyone have any suggestions or further question that might help me improve the speed and range of the newer Time Capsule? Thanks

Just to update everyone:
Today I moved my whole dual network setup to a more centrally located spot in the house. This has definitely improved the coverage of the 2 network bands (n & b/g).
Additionally, since I only recently acquired the TC, I originally just added ("bridged") it off of my existing b/g network. With todays move, I decided to switch the 2 base stations and have the TC and its' "n" network the first connection off of the DSL router. Then reconfigured the older ABS Extreme (UFO) to "bridge" off the the TC. While I am convinced that I did not originally have the 2 networks co-mingled (as early speed tests confirmed), I seem to be experiencing improved internet speeds in the 5Ghz ("n") network. Could this be due to no longer "bridging" the TC through the older ABS Extremes' internal Ethernet switch?
As per Tesserax suggestion, I then did a Signal-to-Noise ration (SNR) survey of the house, and came up with some good results based on the SNR Guidelines in Tesserax comments above.
35 to 45 SNR throughout most of the house. About 25 SNR just outside in the patio where I was barely getting a connection before. Things have definitely improved. And I am very pleased. Clearly network speed is the advantage of 802.11n technology.
Nevertheless, my original observation still seems to apply. Here's why: Detached from the house is the garage and an office. As I moved out toward the office during the SNR survey (about 50 ft. away), the strength of the 5Ghz ("n") network dramatically dropped off, and was eventually non-existent inside the office. Yet I could switch over to the 2.4Ghz ("b/g") network and easily browse the internet.
Apple's marketing claims "AirPort Extreme delivers data transfer speeds up to five times those of previous-generation 802.11g wireless networks — while achieving up to twice the range."
Now I fully accept, as Apples' footnote states, "Based on a comparison with Apple's 802.11g products. Comparison assumes AirPort Extreme network with 802.11n-enabled computer. Speed and range will be less if an 802.11a/b/g product joins the network. Accessing the wireless network requires an AirPort- or AirPort Extreme-enabled computer or other Wi-Fi Certified 802.11a/b/g-enabled computer. Actual performance will vary based on range, connection rate, site conditions, size of network, and other factors. Range will vary with site conditions." If "site conditions" are limiting the range of the 5Ghz band, why aren't those same site conditions limiting the 2.4Ghz band as well. While I don't realistically expect a full doubling of range between the 2 bands, couldn't I expect SOME? Otherwise the marketing claims are meaningless.
Can the disparity be explained by Tesserax' observation above, "we know the stricter the wireless security employed, the more overhead is "eating away" the overall bandwidth so we would expect poorer performance when using WPA2 vs. WEP." Now the TC only has WPA2 security available. Are we to assume that Apple's range claims do not apply to the TC then? If I switch my older ABS Extreme (UFO) from WEP to WPA2 will the result match Apple's marketing claims? I'd rather not chop off my good right leg just so it will match my missing left leg. Perhaps my expectations for 802.11n technology were a little too high. Don't get me wrong. I'm very happy with the results. And I am thankful for Tesserax advise. I also appreciate the fact that I am not (yet) experiencing the difficulties that others here are having with the Time Capsule.
Ultimately, I assume that picking up an Airport Express "n" will extend the 5Ghz network into the office. Is this correct? If anyone has observations on this or my thoughts above, feel free to share them with the rest of us.

Dual Monitor Set-ups (opinions please)

So I'm finally ready to jump into the dual monitor set-up. Right now I'm using a single 19" widescreen monitor. I recently started doing more work with movies and it would be absolutely wonderful to have the movie on a separate monitor.
Does anyone have any suggestions or recommendations for moving to this type of set-up? I want to make sure I buy something that will do the job for a long time.
Thanks in advance!

Hello Pal, Sorry for the late response... but this is what I use (Note: I have a laptop)
http://store.apple.com/us/product/M9321G/B?fnode=MTY1NDA5OQ&mco=MjE0NTg3Nw
I believe this is exactly what you'd need (there is no additional software needed)
You just plug it in, both screens flash a light color blue for about 3 seconds and you're off.
The only downside is if you are used to using your hot corners, when the screens are split you have to move your move a whole other screen length.

"Dual loop setting" in MAX

1) I use the shift register just to get the last data, i.e. the VISA resource name. Without the shift register, it is an array and it cannot be wire to the VISA close. This may looks stupid..so what about to avoid the For loop, as in this VI attached? The driver for the oscilloscope is available at http://sine.ni.com/apps/utf8/niid_web_display.model_page?p_model_id=485.
A tunnel coming out of a For loop will often default to an autoindexing tunnel and give you an array. You can right click on that tunnel and select disable indexing to get a normal tunnel coming and not the array. I'm not sure why the need for the For loop, unless you intentionally want to run this code exactly 180 times.
2) I never modify the arrangement of VISA write and VISA read. It is given in the driver for the oscilloscope. So I assume that it is fine. Is this assumption correct?
I don't know. I am used to serial port communication and not GPIB communication, so my reference basis is that where I am used to needing some sort of delay. In a situation like that if you write then read too fast, there is nothing yet to read. But by the time the loop gets around to the next iteration then there would be something in the read buffer but from the previous iteration. I don't know if the mechanics behind GPIB are inherently different than serial.
3) I already put another Tick Count to compare with. Is this what you mean?
Exactly.
I tried to run and it stoped after the VISA close. Then I close the Labview and rerun this VI. The error occured at the VISA write during the first iteration. Then if I change a new GPIB address at the oscilloscope, MAX and the input for VISA session in the VI, then it can run with no error. This is only annoying for this VI but it becomes a real problem when I combine all my sub VI together later.
Thank you for your help..

Dual network card

Hello,
I have a SAP server with a dual network card. I want to use one for SAP for accessing the network and the other one for iSCSI for provisioning more disk space. Is there no way to do this without affecting SAP's performance? If so, this should be considered a major bug...

Hi
Unfortunatelly there is no date so far. This is described in SAP Note 1135705.

Error: there is a problem connection to the GPRS service in your registered home network, error trying to make data connection. this may be casued by a voice call, a wired activesync connection or inncorrect network setting

like 2 weeks ago i called in to att to see how much is the data plan and it would end up costing $30.
so i was like screw that. well they figured that i got a new phone replacing the LG shine. so they asked
for to call this number so they can recieve data which would updated the system that i have a plam treo 750.
ever since this conflict i can't send picture messages. i get that problem. everytime i attempt to send a picture
i recieve this.
- there is a problem connection to the GPRS service in your registered home network.
- then i get a test that says error trying to make data connection. this may be casued by a voice call,
a wired activesync connection or inncorrect network setting.
please someone help me.
btw. hard reset and soft reset did not work for me.

I've forgotten my Wi-Fi password for a network set-up years ago and am trying to include a new iMac on the same network. How can I do this?

I've forgotten my wi-fi password for a home network set-up years ago on a Powerbook. I'm now trying to add a new iMac to the same network so I can have 2 hooked up. How can I retrieve my password for the network I created or can I set-up a new one? I did try the latter, but it didn't seem to work on the new iMac for some reason. Thanks in advance for any suggestions!

HI, Welcome to the Forums...
The password may be stored in your keychain on the system you set up the original PowerBook.
Run KeyChain access in the utilities filder and see if you have a Airport base station password entry, from this you can reveal the password.

I just purchased the airport Express to use in hotels while traveling to create a wireless network from the hotels wired dsl. A friend said to set up the network from home prior to traveling. How do I set this up? Thanks.

In addition to RyanJC's comments, the 802.11n AirPort Express Base Station (AXn) can store up to five different http://docs.info.apple.com/article.html?artnum=108081 configuration profiles. You will need to use the AirPort Utility to create & save these profiles.
To create a new profile:
Open AirPort Utility, select your AX from the list, and then, click "Manual Setup."
From the AirPort Utility menu, select "Base Station," and then "Manage Profiles."
Click "+" to create a new profile; give it a name, and then, click OK.
Set options, such as network name, passwords, Internet connection method, etc.
When done setting the options, click Update.
To switch profiles:
Open the AirPort Utility, select your AX from the list, and then, click "Manual Setup."
From the AirPort Utility menu, select "Base Station," and then "Manage Profiles."
Click on the desired profile, and then, click OK to apply the new profile and restart the AX.
Just remember to switch to the desired configuration profile before removing power from the AX.

Lion Server VPN dual network cards

I have a XServe running Lion 10.7.3. When I connect to the vpn I can only connect to the server and nothing else on the network. How can I set it up to see the whole network?

Simple. Configure your VPN correctly.
Of course, you might have done that, but since you're so light on details there's no way for us to know.
From your description, though, it sounds like you haven't configured the server to hand out the right range of VPN networks. When a client connects, the VPN server sends it a list of networks/subnets to send over the VPN tunnel - e.g. "hi, client, send me all traffic for 10.1.2.0/24".
If you haven't set this then the the client doesn't know what traffic to send over the VPN vs. sending to the public internet. That's what I assume is going on here, but I could be wrong.
If you have got the routing correct the next issue would be DNS - have you set the right (internal) DNS server in the VPN server settings, so that the server knows to tell the clients what DNS server to use? If you haven't then the client will continue to use its normal DNS server which likely doesn't know anything about your internal network hostnames. Pinging a resource by IP address rather than hostname would be a simple check for this.
So check your VPN configuration and report back if that's not a solution. Either way it likely comes down to a configuration error on the server.
