Modem and/or Router problem?

My old modem and router are connected to my pc and I could get on the internet using the airport on my mac. I had to get a new modem and now my mac won't connect to the internet. It is giving me the following error message: "IP Configuration 192.168.1.64 in use by 00:11:09:13:c8:9b, DHCP Server 192.168.1.254". What does this mean and how can I connect to the internet again? Someone please help me. Thank you.

Problem Fixed.
I finally got a hold of someone who knows what they are doing at my router's company, Dynex.
First, she had me hold down the reset button on my router for 20 seconds.
Then she had me go to my PC's browser and type in the address 192.168.2.1, which brought me to the Dynex home page.
On the left side, under Wireless, choose Channel and SSID.
Under SSID, remove the router name Dynex and type in any other name (example Puppy).
Apply changes.
In mac, open Network, and Airport.
Find Puppy network name, highlight it, and join network.
Connection to internet was successful.

DSL Modem and Wireless Router problems

I started to have problems on Tuesday.
My Equipment is:
Dell Precision 870 PC with a Intel Pro network card
Apple IMAC with the Apple Lan connection
Lynksys/Cisco E3000 (Problem started with a Linksys WRT610N router)
Verizon (Actiontec) GT701C DSL modem
I came down to my office and I noticed that the DSL light on my modem was not lit. In the past
this has ment that there is a problem in the Central Office. Later in the day I got hold of Verizon
tech support and we got the DSL running again with the modem connected to either computer.
When I connect the router to the modem and the computers to the router, Dell via wire and Apple
via wireless 5.0 GHz 802.11N inout and restart both the router and the modem, I get connectivity
through the router and the modem but the DSL light on the modem is not lit. After a long period
of time the DSL light may come on then I loose connectivity.
Everything was working correctly til late Monday night/early Tuesday morning.
I have reset both the modem and routers to factory defaults several time. I have a problem when
trying to get connectivity with the moden after setting it up again and it takes me to the Verizon
DSL startup site. Tech support walked me throuogh using the "192.168.1.1/verizon/redirect" and
shutting the redirect off. I then have connectivity as long as the router is not connected.
I thoought the router went so I just installed a new router, the Linksys/Cisco E3000, and I still
have the DSL light problem.
Solved!
Go to Solution.

Having both routers the same IP address is a little bit confusing, but possible since each router creates it's own subnet and provides full PNAT support. Actiontec DSL modem has to have DHCP enabled since Linksys WAN (not LAN) port should be connected to one of 4 Actiontec LAN ports. Linksys should not have any configuration setup in regards of your WAN account. Just set it to dynamic address. In ohter words:
1. RJ-11 connect to Actiontec mode/router.
2. Actiontec modem should be configured to acquire an IP address from Verizon and to provide all authentication info to Verizon.
3. Actiontec modem should be configured to allow clients to acquire dynamic IP addresses -- DHCP enabled.
4. Linsys WAN (not LAN!) port should be connected to Actiontec LAN port.
5. Linksys should be configured to acquire dynamic IP address and no authentifacations.
6. Configure Linksys to be DHCP enabled or you can use static IP addresss if you want.
7. Wireless devices would be connected to Linksys and on the way to the Internet addresses would go through double NAT conversions. Any wired device connected to Linksys would have similar features. Any device connected to Linksys should be able to connect 192.168.1.1 assigned to Linksys, but not to Actiontec.
8. To be able to connect Linksys and Actiontec would no be able to communicate unless you split 192.168.1.0/24 into smaller subnets and set specific routes in the table. But even you do so you will not be able to access 192.168.1.1 accross subnets boundary.
Hope it helps.

I have one PC with a modem and linksys router #BEFW11S4 installed. I have 3 other PC's which connect to it via Linksys wireless-G adapters. Things have been working just fine until recently when now at least twice a day my Pc's with the adapters lose connection with the router. Any suggestions?

Verizon DSL, Westell 6100 Modem and Linksys router

If anyone is having a hard time getting these three to work together to get on-line, I know your pain. I've spent the better part of two days trying to get these devices to talk to each other. After hours spent trying different combinations and little to no help from Verizon and Linksys I have finally gotten my DSL up and running through my Linksys router. I post this in hopes that someone doesn't spin their wheels like I have been doing over the past few days. Here's what I did to get them to work:
1. Reset both the Linksys router and the Westell modem
2. Unplug the router and the modem
3. Connect an ethernet cable from your Apple to the Westell modem and power it back on
4. Type 192.168.1.1 in the address bar of your browser of choice. The username should be "admin" (w/o the quotes) and password should be "password" (again no quotes)
5. It will ask you to update your username and password
6. Under the CONFIGURATION heading select VC CONFIGURATION and click on EDIT
7. Make sure that both PROTOCOL and MODE are set to BRIDGE
8. Click on SET VC and then click OK when asked if you want to reset for new configuration to take affect
9. Once again power off the modem for about a minute then power it back up
10. Login again with the login you created above and go to the STATUS/ABOUT column and write down the MAC address
11. Set it to DHCP OFF and change the Private Lan Modem IP to 192.168.2.1. Write this down and keep it so you can access your modem in the future.
12. Save the settings. You will lose communication with the Westell at this point. Once again, power down the modem for about a minute.
13. Connect the ethernet cable from the modem into the Internet port on the Linksys router and then connect your Apple to the first ethernet spot
14. Turn on both the Linksys router and the Westell modem
15. With your browser (Safari or Firefox) type in 192.168.1.1. Under SETUP go to MAC ADDRESS CLONE and enter the MAC address you wrote down for your Westell modem earlier and then save the settings
16. Make sure you are in DHCP mode and not PPPoE
17. Save, exit, and you should be on-line
That was a lot more difficult than it had to be. I certainly didn't get this from the support folks from Linksys or Verizon...a lot of trial and error and investigating on-line. I hope this saves you from the headaches I experienced.

Feedback for Linksys:
In the Linksys Help system "Easy Answers" there's the question "How can I set up a Linksys router with DSL Internet?" This is what I used to try and solve my Internet connection problem.
The Answer says "Most DSL providers use Point-to-Point Protocol over Ethernet (PPPoE) ..." and goes on to explain how to set up the router for PPPoE. However, my service (AT&T/Yahoo high speed internet) uses DHCP. That meant I spent several frustrating hours trying to get it to work with PPPoE.
The Answer would have been better if it first explained how to tell if you have PPPoE or DHCP (see the reply from vness above, it's an excellent explanation), and then linked to the appropriate setup instructions.
Thanks for the help!!!!

Netgear Modem and WRT54GL Router

Hi all,
I have a wired network using a Netgear Modem and have recently decided to implement a wireless hotspot for users to connect via their wireless laptops etc.
Because of the DHCP facility in the WRT54GL router (allocating ip addresses automatically etc.), I was recommended to this route.
What I'm sitting with is that the Netgear Modem's default IP address is 192.168.0.1 and all my wired desktops are setup using IP addresses following on from that (e.g. 192.168.0.100 / 192.168.0.101 etc etc.)
The Linksys's default IP address is 192.168.1.1
I've managed to change that to 192.168.0.2 so that it can be seen on the same network, but now:-
1.) How do I access the router's adminstrative settings (previously it was : IE Browser > typing in 192.168.1.1 and inserting my username and password and I was in). When I go to IE Browser > typing in 192.168.0.2 it says it cannot "display the page" and no matter what I do, I cannot get to access it. I can ping the 192.168.0.2 address and replies so it is connected etc. Any suggestions?
Also, I've installed a 2nd PCI card in my server (that controls the internet access to the desktops etc.) and shared the internet connection from LAN1 (onboard motherboard network port). I've connected the Linksys WRT54GL Router via a cable from the LAN2 port to Port1 on the Linksys. Linksys DHCP setting is disabled as well. What should happen is that when a wireless laptop connects to the internet, the DHCP should allocate an IP address to the laptop and should be able to have access to the internet.
2.) On the wireless laptop, when searching for a wireless connection, I can see the Linksys Router and can connect. I have connection as Skype connects perfectly but yet, I cannot access the Internet. When typing in a website address, it comes up saying "Unable to Display Page". If I type in http://216.239.51.100 I get the google home page but if I type in the web address, nothing !! I have been told that it could be a DNS problem but no one can tell me how to fix it. Any suggestions?
Can anybody out there shed some light on these 2 issues?
Thank you
Heinz

Moving BT Infinity modem and HH3 router to another...

Typically my master socket is in the dining room and all my IT kit is two floors up. Was using HH3 as Total Broadband in my loft with ethernet connection out to my Apple Airport Extreme which ran the network - everything hunky dory but I wanted faster speed - hence Inifinty.
BT Engineer had a look at my set up, started talking of bringing in a hoist into my back garden to install new Master Socket and it just seemed easier to install in the dining room and use the HH3 as router and re-configure my network - wrong! Most devices lose contact with the HH3 on a regular basis, therefore I want to re-look at installing Infinity into the loft and revert the HH3 to a ethernet connection out to my Airport Extreme. I understand all the engineers do at the master socket is install an Infinity faceplate. I've tried replacing the loft extension with a split front BT master socket and moveed the Infinity faceplate - result; voice remains but no DSL on the white Open Reach modem.
Are there any suggestions what I need to do? The original extension had four wires connections (white & blue, blue, orange & white, white & orange) but the BT master socket only has three positions and my original master socket only has two wires connected.
Thanks, Andy

Hi Andy and welcome
In THIS POST Phil recently wrote.-
"Very proud of myself this afternoon. I'm not much of an expert when it comes to DIY but I have managed to hardwire the router from the back of my house to the office on the first floor at the front. After much contemplation, I decided to buy some external cat5e cable and run this along the same points as the SKY feed. The result looks pretty good and I can now get 37.5Mbps upstairs as well as down. Result."

Suggestions for Cable Modem and Wireless Router

Hey everyone!
I have the new iMac and would like to have a faster wireless router. Currently using an old D-Link Wireless G router and would like something like the Time Capsule (as it has Airport Extreme in it) or Netgear Rangemax Dual Band Wirless-N Gigabit Router. My problem is, my Internet is through my cable company, so it comes into the house as a cable connection. It appears that these two combos would still require the use of a cable modem.
Any suggestions to keep the equipment down to one piece? If not, any suggestions for a cable modem so I can return this old one to the cable company?
What would be the best/quickest wireless router?
Thanks for your help!

Go to your ISP's web site and do a search from your ISP for compatible cable modems. Then buy the capable modem your ISP says that is comp[atible. On the new cable modem find the Serial number & MAC address, make then call your ISP tech help desk and tell them the new modem you got and he/she will ask you that information. When the ISP tech says they can see/ping that new cable modem then it will work. Then connect a new cheaper Airport Extreme and any external USB2 hard drive to connect to that new Airport Extreme. I say this because Apple put out and Update a little while ago that will allow an external connected to an Extreme as a Time Machine disk.
PS: Remember the old trick of checking you Ethernet cables. I can't count how times I have seen professionals install all new high speed switches, routers, etc. and wonder why no speed is seen. Then after numerous trouble shooting they discover they used the old 10 Base T cables and just changing the cable solved their problem.
Just make sure you do this one at a time starting with getting the ISP compatible cable modems list to know what cable modem you can buy (to save that monthly ISP rental fee). Then you can get the going as long as so speak with your ISP tech to give them that new cable modem Serial number and MAC address so they can register it with their servers.
This will be to easy as long as you do things in step.

Can I use an Airport Extreme as a modem and wireless router?

I realize this shows my ignorance, but I am wondering if I need to lease my isp's (Comcast) modem or if I can use and Airport Extreme instead. Thanks for your help.

AirPort Extreme is a router only.....no modem on board.....so you will need a modem to work with the AirPort Extreme if you want to be able to access the Internet.

Motorola Surfboard (combination modem and wireless router) plus Airport time Capsule - 2TB

I am reading all of the discussion posts regarding the new OS Lion and starting to become wary. Here is my pridicament:
I have 3 PS3 game consoles (2 are wirelessly connected to the Motorola Surfboard),
3 PC laptops (also wirelessly connected to the Motorola Surfboard)
My thoughts were to purchase the Airport Time Capsule with the new IMac and possibly set up a wired connection to the Motorola Surfboard with the Airport Time Capsule, then provide a wireless connection for all of the Apple products in my home as well as a back up file system. Mind you I have 3 IPhones, 2 IPads, and will be purchasing a new IMac with Retina Display and an HP - LaserJet Pro MFP M1217nfw Network-Ready Wireless Black-and-White All-In-One Printe.Will this be too much on one modem? and has anyone else even tried this type of configuration?
As smart as I think I am, I am hesitant on making this purchase, and sometimes I feel that sales reps at retail stores tend to be over confident in their knowledge of a wireless home system.
Any thoughts on this would be greatly appreciated.

Certainly not.
The limiting factor is likely to be your ISP's delivered speed. Whatever bandwidth you have will be shared among all the devices. If they're all streaming video at the same time, for example, one or more of them may become slow.
You don't need to purchase a Time Capsule simply because you're buying a new Mac. The iMac can join any network.
The Time Capsule can replace the router function of your existing combination modem / router, or it can join your network as either a wireless or wired client. If you want to use it for Time Machine backups, you should favor the latter. It can also create an additional wireless access point if you so choose. The Time Capsule is a very capable full-featured router but if you don't need a router or additional access point, then you can use any external HD for Time Machine backups. That would be a lot less expensive.
Lion has already been superseded by Mountain Lion. A new iMac will ship with Mountain Lion installed.
Only certain model MacBook Pros and iPads have a "retina display" - no iMacs.

Airport Express and Linksys Router Problem

I have a Linksys wireless router through which I connect to the internet using my Macbook Pro without any difficulties. I recently purchased an Airport Express unit in order to connect to my stereo and play music using Itunes. However, I seem to be unable to set up the Airport Express as the Airpor Utility does not seem to be able to find it. I tried connecting it to the router using an ethernet cable and this did not seem to solve the problem? Does anyone have any recommendations to solve this problem?

Thank you for the suggestion. That allowed me to see it to configure it but once I disconnect it to restart it I the network cannot find it and it just blinks orange. I am guessing that it is because I have set the network security incorrectly. I set it at WEP 128. How do I check to see how the Linksys is configured? Or do you think it might be something else? Thank you.

AEBS and Vigor Router problem. Can anyone help?

I've a small home network running an Airport Extreme Base Station, An Airport Express, a 350GB disk and an ADSL modem. The only computer on the network is a MacBook Pro, although my iPod also connects through it. This worked flawlessly for the past 12 months, until the modem provided by my ISP died.
I struggled with a NetGear ADSL modem for a couple of days, which the AEBS couldn't see. Following comments elsewhere on this site I returned it, and bought a Draytek Vigor110, as this seems to be the product that segues most effortlessly with the AEBS. This morning I managed to get the thing up and running, wirelessly connecting the laptop to the internet, however I appear to have lost the rest of the network.
The Airport utility can no longer find either the AEBS or the Express, nor connect to the hard drive. The iPod will not connect at all. The laptop steadfastly refuses to pick up any wireless devices in the area, despite being currently connected to the Internet via one of them.
Any ideas? The Draytek support is non-existent and I'm not particularly clued up on DHCPs, PPPoE, subnets and all that jargon.
I'm guessing that I've done something wrong with the Bridge mode - but as I can no longer connect to the AEBS I've no idea how to sort this out.
Thanks for your time.

hi what you need to do is reset AEBS and connect the WAN port to the vigor and for setup point only the macbook pro to the LAN open airpot utility and connect to the AEBS you need to set the internet connection to PPPoE and enter your username and password for your ISP and also set share a public IP address. you can set up the WiFi side as you like.
there are not settings for the vigor as it only coverts ADSL PPPoA to PPPoE.
i use a lot of vigor 100/110 with there Vigor 3300 routers and all you do is just plug the in.

Internet Connection Sharing and NFS route problem?

My new box is yet to gets its wireless card so following the wiki I have painlessly set up ICS - this works great. The ICS host connects to my wireless router on wlan0 and to the ICS client on eth0. The ICS client attaches on eth0.
From the ICS client I can ping eth0 and wlan0 on the host and also the router but I can't access the NFS shares on the host - should I be able to access them on both wlan0 and eth0 - even if I bring down wlan0? I'm guessing I need another iptables rule...

I'm not quite sure I understand whats happening here.... So here is a "diagram":
ICS cli --- eth0 ---> ICS host --- wlan0 ---> router ---> internet
Yeah? From this, there is no reason for wlan0 to affect NFS from cli to host, assuming everything has been set up properly with the routing tables.
If you disable all iptables stuff (which is how I'm assuming you have the routing working), does NFS work? Have you set up your /etc/exports properly?
Can I see your iptables stuff as well?
And on a side note: I recently chucked NFS in favour of sshfs, it's much better for me personally. Considered that?
