Linksys Router- Assign IP Address?

I have a Linksys router with my Mac Pro. I have my mac pro wired into the router but it is a wireless router so there are other things on the router as well such as the Xbox. I have to have certain ports open for the Xbox to work and my torrent client to work as well. Sometimes the router auto assigns the IP to my computer and then I have to go into the router settings and change which IP has which ports open for it. Is there a way to assign my computer an IP so it gets the same IP every time and same with the Xbox?

Open Network preferences click on the Advanced button then on the TCP/IP tab. Note the IP address assigned to your computer by the router, then change the TCP/IP IPv4 Configure drop down menu to DHCP with manual addressing. Then insert the IP address your router was using under the previous setting. Click on the Apply button. Use this IP address in your port forwarding configuration.

Apple TV2, Linksys Router, Preferred IP Addresses not being taken

I'm setting up every internet enabled device in my household on a preferred IP address inside my linksys router. This is in case of any future use where I may need to port forward to a specific device. I am setting up the preferred IP addresses in the Linksys instead of adding Manual addresses to each individual item as not only does that add to the process, it's not very friendly when trying to change the order of IP addresses I have done, or if a new item is added to the household. Plus Manual addresses can be deceiving if there are network errors.
The devices we have: iPhone4, iPhone4S, iPad 3rd Gen, Airport Express, Apple TV2, Mac Mini and a PS3.
The Router: Linksys WRT120N fw1.0.07
The Linksys requires the MAC addresses of each device to assign the preferred IP Address to each individual device. I have even gathered up the Wifi and Ethernet adaptors MAC addresses for the items applicable. All devices are properly eing assigned the right IP address... but no matter what I try, the Apple TV2 always pulls a basic 192.168.1.100 IP even though its airport MAC address is assigned to grab 192.168.1.143 and ethernet is 192.168.1.142. Neither the ethernet nor the wireles settings of the ATV2 grab the right ones.
Has anyone else encountered this issue? If so, how did you finally push the right preferred IP address to the device. (Keep in mind that I want to grab the items automatically, I want to have the linksys supply the preferred IP and not have the ATV2 grab a manual address)

Hi… Make sure that you have entered the MAC address of your Range Expander under MAC filter. You don’t need the filtering to be done on Range Expander. Try changing other wireless settings such as Channel to 11 etc… Also make sure that you are assigning an IP address that is in the range of the router. Go to wireless network connection properties, under wireless network, click advance button and select ‘access point, infrastructure networks only’. I think this should solve the issue. Upgrade the firmware on the router and range expander if needed.

Installed Linksys Router but IP address shows Netgear Information

Trying to setup security for my Linksys Router that I didn't do when I first installed it, but when I access the Routers IP address page, Netgear information comes up. How is this possible? I had the Linksys rep on line trying to get help, and she got real testy with me when I told her what was happening. Any advice?

Is this cascaded then to another router? How does your connection go? Modem to Linksys router then to computers? Or do you have other devices namely of course a netgear device connected to your network?
Go to start --> run --> cmd and type in ipconfig. What is your default gateway? That should be one that you should attempt to type to access the router configuration page.

Subinterface FE router: assigning ip address

Wnat to connect 1 FE port of switch with 1 FE port of router (2800). As we need different subnet for voice and data wanted to 'subinterface' FE port on router. But when tried to assign ip address on FE 0/0.1 I got '% Configuring IP routing on a LAN subinterface is only allowed if that
subinterface is already configured as part of an IEEE 802.10, IEEE 802.1Q,
or ISL vLAN.'. How do I get this fixed? First but interface (or subinteraces in a vlan?or..)
Thanks

Hi Peter,
Before assigning the IP address you need to set the encapsulation on the interface and then it will take the IP address.
Please give the command under the subinterface
encapsulation dot1q 1 native ---> where 1 is the vlan number.
subsequently for different vlans you need to repeat this command under diff subinterfaces.
encapsulation dot1q 2--> for vlan 2
encapsulation dot1q 3--> for vlan 3
Native keyword you have to use for vlan1 only as that is the default native vlan on the switch.\

Linksys router and IP address problem

My linksys router is sending out a fake IP address of 24.124... Is there any way to set it so it sends out something else? I'm trying to access a chat server which banned ALL 24.124 addresses because of some hacker doing a number on their server. I really want to get in without having to buy another router. I have a WRT54G V5

If the router is not giving the 192.168.1.x ip, the router might be acting as a pass through already and needs a firmware upgrade. If the firmware upgrade will not save the router, it might be defective.

Why does my Airport Express say "self assigned IP address"? No IP address for the ethernet, and it is not connecting to my cable router any longer...

Why does my Airport Express say "self assigned IP address"? No IP address for the ethernet, and it is not connecting to my cable router any longer...

Some cable providers.....like mine, a well known company......seem to take anywhere from a few moments to sometimes up to 30 minutes to allow their equipment back at the cable company to fully reset and issue a new fresh connection.
So, it would not hurt to leave things powered down for 15-20 minutes or more when you perform the reset that John Galt suggests.

Why assign IP addresses to router/switch interfaces?

I get why I would ever want to assign a IP address to a router or switch, for remote login and IP for hosts to reach it. But why assign IP addresses to the interfaces? Is it so the router/switch knows which port to send the packet out? Route summation? But I thought they do that through the routing table, like " that address is out this port".
So why would we ever need to assign IP addresses to specific port interfaces?

You normally assign IP addresses to L3 interfaces so other L3 devices have an IP address to forward traffic to. (L2 IP address are generally only used for management.)
Suppose you had Host (192.168.1.5/24) <> R1 <> R2 <> (192.168.2.8/24) Host, and you want the two hosts to intercommunicate. How would you get this to work?
You might started by providing interface IPs on the router interfaces facing the host, such as:
Host (192.168.1.5/24) <> (192.168.1.1/24) R1 <> R2 (192.168.2.1/24) <> (192.168.2.8/24) Host
You then configure "gateway" IPs on both hosts:
Host (192.168.1.5/24 - GW 192.168.1.1) <> (192.168.1.1/24) R1 <> R2 (192.168.2.1/24) <> (192.168.2.8/24 - GW 192.168.2.1) Host
Now each hosts "knows" to send all its off local subnet, traffic physically to the GW IP. So, for example, if 192.168.1.5 want to sent to 192.168.2.8, it would forward the traffic to the GW IP, 192.168.1.1. This is a example of why you want an IP on the router's L3 interface.
Next we want R1 to forward the packet to R2, but it too needs a "next hop" IP address, so we assign addresses on the link between the two router, e.g.:
Host (192.168.1.5/24 - GW 192.168.1.1) <> (192.168.1.1/24) R1 (192.168.3.1/24) <> (192.168.3.2/24) R2 (192.168.2.1/24) <> (192.168.2.8/24 - GW 192.168.2.1) Host
R1 then needs to "know" where to send packets with an destination IP network of 192.168.2.0/24, in this case, it need to "know" to send the to IP 192.168.3.2. When it does, R2, having and interface with 192.168.2.1, will also know 192.168.2.8 can be reached by sending the packet out that interface.
Hopefully, the above will show why IP addresses on router L3 interfaces are needed.
BTW, normally for the R1<>R2 link, you would assign a /30 or /31 network or you might use "unnumbered" interfaces (which "borrow" IPs from another interface).

Embarq router set to bridge to linksys wireless router stactic ip address helppp!!!

Problems using MBP as WiFi router for iPad2 (self-assigned IP address)

H/W& S/W:
MBP 15" (model early 2011), running Snow Leopard,
iPad 2 WiFi only, 64Gb, iOS 4.3.4 (8K2).
Scenario:
I am in a location where there is no WiFi. MBP is connected via Ethernet to a DSL network, and has access to the Internet. I turn on Internet sharing, having set the following:
"Share your connection from" set to "Ethernet" and
"Share computers using Airport" ticked.
Previously, I have then connected the iPad 2 via WiFi with the WiFi network created on the MBP, and succesfully worked from the iPad on the Internet (email, browsing, app downloads, ...).
Problem:
Now, however, the iPad connects to the MBP's WiFi network, but when I attempt to access the Internet, I get such messages on the iPad as "Safari is not connected to the Internet" or "Cannot Get Mail ...".
On investigation, I see that Airport on the MBP is in a YELLOW status: Status On, with the note "Airport has the self-assigned IP address 169.X.y.z, and will not be able to connect to the Internet".
On the iPad, the WiFi network shows the IP address 169.X.a.b (with a subnet mask (255.255.0.0).
I have tried:
1. turning Airport off and on
2. renewing the DHCP lease on the MBP
2. configuring IPv4 address in the MBP manually
3. configuring the IP address manually on the iPad (not expecting anything with this, but ....)
4. fixed Permissions" on the MBP disk (suggested on another support community web site)
But none of these make any difference.

forgot to mention: Firewall is disabled on the MBP.

Hello,
I've had the exact same problem on my macbook and it really **** me off ! I tried all of the solutions written in this forum and none worked for me ! I was really starting get mad especially that my macbook is quite new...
And the thing is i have no Apple Store where i live which is a pretty F***g problem so I had to wait for vacations to go to france where I took my macbook for check at the apple store...
I just came back right now and my wifi works till now a least far much better than before...The guy was really nice he checked everything and he tried all the solutions on this forum too..Finally he tried to boot from one of '' apple's '' usb that has suberb booting systems...And it worked so finally he re-installed 10.6.5 as it was '' corrupted '' with wifi bugs ! For that he needed to delete everything on my macbook ! GREAT !
After 15 minutes the installation was done and it started like when you buy a new macbook !
And VOILA the Wifi came back to normal !
Hope this helps...
If you have this problem go and see Apple Store or re-install yourself 10.6.5 !
Thanks !

Self-assigned IP address problems

I'm having a problem with my wireless router connection (my Airport card shows the network, but the "fan" is greyed out, and if I choose the network it still doesn't connect - When I check network status I get "AirPort connected to network, but has self-assigned IP address and may not be able to connect...)
I can temporarily fix the problem by going into System Preferences to Network to Airport to Preferred Networks to Assist Me and THEN it will go to my network and turn on the path.
I'm running Tiger 10.4.11 on a G5 iMac with the original AirPort Extreme card, and routing through a Linksys WRT54G attached to a cable modem.
There are a lot of networks in my area, according to my wireless "fan".
If changing channels on my router might fix this, I'd like to give it a try, but I don't know how, AND I don't want to ruin the signal to the other computers in the house, which, by the way, work just fine when the iMac loses the signal.
If there's another way to tell the router to ignore the self-assigned IP address, or to get the AirPort to stop providing this ...
The problem is obviously the self-assigned IP address. The question is what is causing this?
Is it the AirPort Extreme Card?
Is it the Linksys Wireless router?
How do I test to see which it is, without losing the signal from the router to the other computers in the house?
With so many people having the same problem, there must be an answer somewhere.
Can some kind soul please point out the correct path? My tech support (teenager) will be home from college this week, and if I can prove to him that it won't ruin everything I think he'll be up to the challenge.

Hi,
Thank you Linc & dwb, I've had no issues with the router in the 14 months its been installed. But tonight I've turned off the NAS and since then no drop off for wifi/ or assigning itself an IP address.
I will switch on the NAS once again and see what happens, would it be best to assign a static IP to the NAS? One thing I have found when checking the homehub connection details, the mac air connects at the 5Gz Wireless as does the Kindle, which has also suffered from losing the wifi connection, where as my macbook pro only connects at 2.4Gz and like I said has not had any issue. Not sure if this anything to do with the problem or not?
All I do know is that since the NAS was introduced then the problems began, so again not sure if its the NAS impacting on the router or a router setting?
thanks

Self-assigned IP address problem - My solution

I am new to this board and created an ID just to write this post. When I searched for this self-assigned IP problem, I found almost 1 million results on Google so obviously I am not alone.
I have this problem off and on on the wireless network at home with a Netgear router. It has never happened at my office with a D-Link router. Never happened at Starbucks or McDonalds (yes, they all offer WiFi here). But it happened at one Pizza Hut and it also at Christchurch airport about a week ago.
Deleting one of the plist files worked once at home many months ago but this week nothing worked. My Mac usually goes back to normal by itself after I "****" it out at other WiFi networks but not this time. As a last resort, I asked my brother (our family's I.T. guy) to change the router as I had not tried that fix. He didn't do it but a day later, he gave me to oddest solution that worked in a blink of an eye.
The solution? Key in a wrong password!!!
1) Go to Keychain Access, delete the keychain for the problematic network.
2) Connect back to the network
3) Enter a WRONG password that is similar to the right one. For example, if your password is Apple123, try APPLE123. You should still connect to the network and get a self-assigned IP.
4) Repeat Step 1. To be safe, you might want to re-boot now. I did but probably didn't have to!
5) Repeat Step 2
6) Enter the right password
I'm not all that techie so all I understood from what he said was:
1) It's probably a non-Apple router bug
2) It's a hex key problem. The password wasn't being encoded/decoded properly so the router wasn't assigning the computer an IP address. Wasn't even reading the password which is why I could connect with a wrong one.
He deduced that from reading a post from a guy in Spain who thought he had carelessly entered the wrong password and was wasting the community's time with his posting. I had read that post a couple of days ago too! But obviously I thought the Spaniard had just entered the wrong password and there was no fix for me to try out. My brother is a genius!
I guess it then makes sense why fixes like:
1) Disabling the firewall
2) Deleting preference lists
3) Deleting keychains
4) Changing the router
5) Renewing DHCP lease
6) Resetting the router
...have worked for many people and not others. None of them actually fix the cause of the problem. Having searched for 3 days, I could not find the REAL reason why this happened. Personally from all I have read, I think it must be a hex key problem with Netgear and Linksys routers. I see those 2 names mentioned a **** of a lot. Maybe it's another one of those gadgets built more for PCs that don't work perfectly with Macs all the time. We used to have an Apple Airport Extreme base station but that got fried by lightning. It was not cheap.... So technically, it really isn't Apple's problem. I think if we used an Apple router, we wouldn't have a self-assigned IP address. Maybe that's why they haven't "fixed" the problem after so many years.
Anyway, let me know if my brother's fix worked for you.
This is my good deed for the weekend! Goodnight....!

Hello, thanks for the tip/post, & a warm welcome to the forums!

Airport self-assigned IP address, no internet

We got a new router from Verizon and my Mac will not connect. Network Status gave this message: 'Airport is connected to the network xxxxxx. Airport has a self-assigned IP address and may not be able to connect to the Internet.
How do I fix this an get connected to the internet?
Thanks in advance,

I have also encountered this problem and I have been researching it all over the internet all evening and trying everything I could find a suggestion for. Here's what I have: Two G4 Powerbooks, one is a 550MHz 15" Powerbook, the other is a 1.5 GHz 17" Powerbook, they are both running 10.4.11 with all the updates that Software Update has to offer, the 17" is connecting via built in Airport Extreme card, the 15" is connecting via Sonnets Aria Extreme PC card. I have AT&T DSL and I'm using the 2Wire modem/router they provided me with. Neither of the Powerbooks can connect wirelessly to the internet. Furthermore, they cannot even ping the wireless router. 4 days ago, both were connecting without any trouble (and had been able to reliably every day since the beginning of August when I hooked everything up). I have made no changes to my router's settings over the weekend. Nor had I made any changes to the Powerbooks' settings during that time. It just stopped working. If I wire one or both of them to the router with ethernet cables, connection works fine. My Desktop G4 which is normally wired into the router via ethernet, connects fine so I know my internet service is available.
So far, I've restarted both machines numerous times, restarted the router numerous times. Reset the WEP password. Changed the wireless security to WPA. Changed it back to WEP. Trashed the airport plist. deleted every wireless network entry in Keychain. Disabled DHCP and assigned IP numbers manually. Changed the wireless channel (I've tried 1, 6, and 11 with and without interference robustness).
I've been reading posts about this issue on half a dozen web forums (dating back to as early as June 2004). It appears to affect a variety of routers (2Wire, Netgear, Linksys), a variety of machines (Powerbooks, iBooks, MacBookPros, iMacs) a variety of OSes (10.3, 10.4, 10.5).
This thing is really getting me down. Anybody have any other ideas?

MacBook Pro will not dectect Linksys Router

I have recently aqquired a MacBook Pro and i'm at a loss as to why airport will not dectect my Linksys WRV54G wireless router, yet it will detect other secure and non-secure routers in my neighborhood. The MacBook will connect fine to the router via an eithenet cable and work correctly. I have an HP mobile workstation which works fine with the router wirelessly.
To date I have:
rebooted the router several times.
removed the WEP security from the router.
assigned the MacBooks mac address to the router allowing it permission.
I am at a loss as to why it will not dectect the router. I know airport is working fine and so is the router. Any help or suggestions would be greatly appreciated.

Have you tried a different channel?

Airport Connects but has Self-Assigned IP address and no internet

All right Apple this is some Bull#@$% I own 3 Apple units One is a MacBook Pro, one is a Macbook and the other is a G5 Dual processor tower. The MacBook and Tower are using OS X 10.5.5 and the MacBook Pro has OS X 10.4.11. Ok here is my problem all of a sudden all 3 units that had been connecting to the same wireless router for the past year started saying (AirPort has a self-assigned IP address and may not be able to connect to the internet) Apple Care suggested replacing the router well I did that and hello I have the same message. Its connecting but not going to the internet. Under network status I have green lights for Airport and Airport settings a yellow light for network settings and red lights for ISP, Internet and Server. I have this problem with both MacBooks both at the library, my friends house and my neighbors house thats 4 different wireless networks that do the same dang thing. I need help!!

Isolate linksys router from LAN while retaining internet

Hi guys,
got a bit of a problem that I've spent the past 3 hours trying to nail down. My main router is a MI424WR for my FIOS connection. It serves several computers, wired and wireless. I have an old linksys BEFW11S4 router that I am trying to use with a weaker (WEP) encryption so some devices can still use internet that would not otherwise access a WAP or WAP2 access point, and since WEP is easily crackable, I would like to isolate the WEP router (linksys in this case) from the rest of the internal network, which contains shared files)
As it stands, I have connected the WAN port of the linksys to one of the LAN ports of the MI424WR, assigned 192.168.2.1 as linksys' IP address (on a separate subnet, as the FIOS router has a 192.168.1.1 address), received a DHCP Internet address from the MI424WR, and have also enabled DHCP on the linksys router itself in order to allow client devices to get their own addresses and access the internet.
Now, based on what I've been reading, connecting the main router's (MI424WR) LAN port to the WAN port of the linksys should create two separate LAN segments, which should separate the local networks from one another. There is obviously something I'm missing here... I am getting essentially the same result as connecting the LAN port of the FIOS router to the LAN port of the linksys router. Shouldn't there be a difference between the WAN and LAN ports in this case?
Any help is appreciated.
Thank you.
Any suggestions?

The hookup that you did will only protect the BEFW11S4 users from the MI424WR users.   It will not protect the MI424WR users from the BEFW11S4 users.
This is because the WAN port on the BEFW11S4 only blocks unsolicited data coming into the BEFW11S4. The WAN port does not block any outgoing data.
The solution to your problem is this:
MI424WR ---- BEFW11S4
                ---- WRT54G (or any other wireless router of your choice)
MI424WR LAN port wired to BEFW11S4 Internet port.
MI424WR LAN port wired to WRT54G Internet port.
No other devices connect to MI424WR, either by wire or wirelessly.
Turn off wireless in the MI424WR.
All wired and wireless computers (and other secured devices) connect only to the WRT54G, which is using WPA or WPA2 and a strong password.
In this setup, the Internet port of the WRT54G will prevent intruders from getting into your secured network on the WRT54G, even if the BEFW11S4 is compromised.
Also the BEFW11S4 and the WRT54G should be using:
1) different SSIDs
2) different encryption methods
3) completely different passwords, that are in no way similar, since someone might crack your WEP password.
4) different channels. There are 11 channels to pick from.   You can use any two channels, but ideally they should be 5 or more channels apart. Channels 1, 6, and 11 usually work the best.
