Newbie in the dark re. cable modems, routers

A friend with a internet biz gave me a 1711 router with 4ews card. I've got the console outlet hooked up and would like to run my cable modem through the 1711. I don't seem to have much luck. I have the input to the router detecting DHCP ok but that's about it. Not sure how to set up VLAN as switch port or trunk.
I have just enough knowledge via community college class to make me dangerous. Any patient people out there want to take a run at this?

Hi Bruce,
I think you would get a better chance to have your question answered in the Small Business Routers section of the forum.
Also, I think your question will require some clarification, do you plan to use the router for NAT? This may help you in this case:

Why has my native windows 7 Pro-64 network to a windows 7 Pro-64 VM has slowed to a crawl and freezes, after the new Arris cable modem was installed?

Please appreciate the details, so the complete situation can be visualized:
The office network:
New Mac Mini PC running Win 7Pro 64, (in boot camp), networked to an iMac running the same Win 7 Pro 64, VM, UNDER Fusion 7Pro.
To review: My treatment rooms former dell PC/running vista business/ running the server and network versions of my Dental practice mgmt & X-ray capture apps, had no probs WLAN to the front desk iMac running the same PC client dental network apps under the same vista business, & Fusion 4. The dell slowly fried its power supply .
I could not wait to replace it with a Mac mini/ boot camp/ win7 pro 64 bit, as it has to run natively to capture X-rays. The front desk iMac was also upgraded to os10.10.3/ Fusion 7pro/ and its own matching Win7 pro 64bit. The iMac is wired and WLAN connected to a netgear d600 router and a Time Warner Cable modem. The modem then failed and was replaced by an arris modem. As the Arris was configured out of the box, the network ran much slower slowed, as compared to the original modem. BUT- The Vonage 2 line phone system stopped working- no incoming or outgoing voices could be heard after it rang. Then twc remote configured it and the phone now works, but the network iMac slowed to a crawl, and now freezes when accessing the Mac Mini PC dental server to edit or enter data. The Mini perfectly accesses the internet via wifi. It accesses the front desk canon printer by wifi, and can print share they the iMac that is wired to the printer, as well, BUT, the network connection is a spinning pinwheel. The front desk imac easily finds the Mac Mini PC server on the network. It connects easily by entering the servers IPv4 address SHOULD THAT last value change. But if data isn't entered in slow motion, the window and app freezes, and has to be force quit by Task Manager!
Cause:
1. I think TWC switched the cable modem from the default- Non Bridged, to Bridged mode. Could this be the cause?
2. The network setting in fusion, on the iMac is auto detect, a setting that always worked with vista and with the new Win7 system, before TWC installed the new arris modem. 3. Switching to NAT does not work at all is there a different setting to use?
3. Does the Netgear Router have to have a port or pref configured so as not to block the Server.
4. might in need an Access Point (I have an extra netgear wdr3400) ).
5. Do I need an Extender that plugs into the AC LINE?
I hope this info helps.
PS:(some addtl info:
1. File sharing works fine between the minis -Mac and boot camp sides and between the iMacs- Mac and VM sides and between eother side to or from either of the 2 computers! 2. Also either office computer and all of my my home macs , (& my iPad, & iPhone), can access each other instantly and flawlessly, with splash top streamer and jump desktop remote apps, as controller or as client! In fact, the front desk iMac can remote control the mini PC AS IF YOU WERE DIRECTLY ENTERING INFO I TO IT!
SO I think it's either a misconfiguration in the TWC cable modem &/or some additional pref to config in the router? Thanks so much for your help, (been using VM's since VPC1. & Win95 in a iMac, 1999, DV MODEL! (TWC BLAMES VONAGE FOR NOT OPENING SOME PORTS IN THE TELE MODEM. Vonage blames TWC FOR NOTopeningj ITS PORTS IN THE CABLE MODEM, when they meant the ports on the Netgear. They have passed the buck for 6 weeks with not even a guess at what to do. VERY FRUSTRATING! Again, thanks to all!

Okay Saint Steven, I'll bite:
I read your description multiple times, very carefully, and I am still confused. May I suggest the following:
* Follow basic troubleshooting procedures. Isolate each individual problem. Don't try to get everything working at once. Make one change at a time.
* If I read your description correctly, the Netgear D600 (??) Router is the office LAN (not WLAN). Connect each piece on the LAN separately one-by-one, and test each piece individually. Get your LAN and its devices working first. Forget about the Vonage and the Arris Cable modem.
* Next, look at your Internet connection. Again, try each piece separately. Depending on how the original cable modem and the new Arris cable modem are configured, you may also have to adjust the configuration of the Netgear D600 Router.
* Finally, if you are still having problems, try to organize your thoughts and presentation before you post again. List each element in your network. List how each element is configured. Be systematic.
"Arris cable modem" does not help much - some are simple bridges, others are routers, etc.
To answer your questions:
1. I can't tell from your confusing description, but I don't think so. It seems like the problems are associated with the system changes you made (replacing Dell, etc.) and the problems seem to be isolated to the local LAN.
2. Auto detect should work, but it is easy to change and test, as long as you change one thing at a time.
3. No. The Netgear router should allow all communications on the local LAN. Could you have put the "server" in the DMZ?
Note: I could not find a Netgear "D600" model in a web search. Do you mean N600?
4. No. I doubt that you need an additional access point. Based on your description, everything appears to connect to the LAN.
5. No. See 4.
To repeat myself:
* Do careful, systematic troubleshooting.
* Provide carefully written, detailed description of your network and system configurations when you ask for help.
Good luck!

The Apple time capsule provides disc memory, a wifi network, and router functions. It would normally be connected to the internet via cable modem. If I wanted to use a wireless cellular connection to the internet, how would I do that?

Cable modem routers

Just wondering if anyone knows, if there are any cable modem routers in Australia ? Just needing to buy a good model.

Linksys Modems/Gateways

I receive a not connected to the internet message several times daily on my iMac connected via airport to a time capsule which accesses the internet via cable modem.. When I input my password to enter network preferences, the connection re-establishes.

I receive a "not connected to the internet message" several times daily on my iMac connected via airport to a time capsule which accesses the internet via a cable modem. Software/firmware is up to date on the iMac (OSX 10.6.8) and Tme Capsule(7.5.2). Browser is Safari 5.1.
When I input my password at the prompt to enter network preferences, all the lights go green (ie... ethernet, ISP etc.) and the connection re-establishes immediately and states "the connection appears to be working normally".
It more of a nuisance than anything and seems to have started ocurring over the past couple of months. I also have a windows XP box also connected to the same cable modem that I never have internet connectivity issues with. I've verified all the physical aspects of the connections and can't see any evidence of any actual drops in the modem logs. I suspect it is just an intermittent communication loss between the Imac and the Time Capsule, but I am not very familiar with Mac equipment yet.
Just wondering if anyone has experienced a similar problem and what you did (if anything) to resolve it?
Thanks.

The AirPort Express will connect to your existing wireless network if the network is using WPA2 Personal or WPA/WPA2 Personal wireless security settings.
So, it can join the network as a client and then provide an Ethernet signal to your Time Capsule.
Be sure to configure the Time Capsule to operate in Bridge Mode so that it will be operating on the same network.

My iMac G5 is not registering the connection of cable modem

Something freaky happen to my computer one morning about a month ago and since then, I haven't been able to connect to the internet.
My computer is set to start up at a certain time in the a.m. and connects to the internet automatically. Recently, it started up before I awoke and when I did wake up I noticed that the my homepage for my web browser didn't load. I could tell moments later that there must have been a brief power outage to the home. I restarted my web browser and then the computer itself to no avail. I still could not connect to the internet.
I don't know a lot about computers from a technical standpoint, but I know a little. I looked at the network configurations to see if anything stood out. The one thing I noticed was the ethernet settings read to connect the ethernet cable to the computer. Since the cable was actually connected. I figured I may have a big problem on my hands.
The other issue I've noticed is the amount of time it takes to startup and shut down. It's not a very long time (maybe 5 minutes), but I think longer than normal or I remember prior to having internet issues.
If anyone has any clue to what may be going on with my machine, I would definitely appreciate some insight. All suggestion are welcomed.
BTW, I called a so called "Mac Specialist" in the town I reside in and was told that my computer's logic board needed to be replaced and it could cost me as much as $600. I most certainly hope that's not the only solution.
Thanks in advance!

There is a possibility the machine may have sustained some
damages due to a power surge, a brown-out or other variation
in electricity supplied to the machine from the grid.
An uninterruptible power supply with an automatic voltage
regulation circuit built into it is helpful to isolate computers
from the variations and unpredictability of some grid power.
This is not a surge protector. Those are not recommended.
You could try and see if repairing disk permissions in the
system by using that option in Disk Utility. Perhaps to
check and repair the hard disk drive, too, by using the
booted OS X installer's version of Disk Utility, is wise.
On the original OS installer packet disc #1 where the
Installer and Apple Hardware Test are located, it may
be wise, too, to run the Hardware Test to see if any
issues are reported or trouble indicated.
A reset of the power management unit or system manage-
ment controller, etc (whichever your model has) could be
helpful, even if it starts up and runs OK after an outage.
{And a re-install of the complete operating system on a
fully erased (wiped, overwritten with zeroes) reformatted
hard disk drive may be a part of this troubleshooting; if
you keep good records of what you do and how it was
done, even a fair tech should be able to tell you more
directly (if they are fair and honest) of the likelihood of
the hard disk drive being the cause of your problems.
-Doing this would destroy all of your stuff in the Mac.}
There is a chance that the hard disk drive may have a
few issues after a power incident, in some cases, a
few bad blocks or sections of the drive may be bad if
the machine's data was affected by an outage; these
can be checked and sometimes successfully repaired
by using a disk utility; some suggest use of DiskWarrior.
Have you been able to test the cable modem itself;
perhaps reset the modem and then reattach the
computer to it; or see if it works with another computer?
Sometimes, even booting the computer in SafeBoot mode
and then login, then choose to run Disk Utility's repair disk
permissions, and then restart the computer normally, helps.
Have you tried a second user account to see if the issue
of connectivity is isolated to the main or admin account?
Usually, all accounts share the main connection settings.
Sometimes, checking and re-affirming settings can help;
at least as part of a troubleshooting path, to see what
doesn't fix it, and hope to find something which does.
If the issue does come down to a hardware repair of
more than a reasonable percentage of a refurbished
Mac direct from the Apple Store online, consider a
different computer. Even the low-end Intel based iMac
is leaps ahead of the G5 iMac. (I still have G4s!)
PS: What are you using to get online?
In any event...
Good luck & happy computing!

What does Verizon offer in the way of wireless modem/routers?

My stepson currently has verizon DSL service and right now has a single port, Westell 6100 modem/router for a wired connection only. He's getting a new laptop and wants to continue to connect his desktop machine directly to the modem/router but wants to connect the laptop using it's built-in wireless "N" NIC.
The issue is that my stepson is VERY non-technical and I feel very stongly that the best direction for him is to go with a wireless modem/router that is provided by and supported by Verizon. Can anyone tell me what make/model of wireless modem/routers Verizon is offering and whether any of them are supporting wireless "N" vs. the older wireless "G" standard?

Hello there,
You are on the right track!
I just traveled this road myself. You're right if you don't use verizon equipment nothing else will work.
Contact verizon DSL support tell them based on your application you want a VersaLink Model 7500 by Westell
It's a 4 port plus wireless combo modem/router.
It will address all your application wishes. Tech support will assist you with the set up.
Trust me you are going to love this Westell hardware.
Hope this helps Good luck!

Airport Express not connecting to the internet via cable modem

Hi. I need help. I just bought an airport express to get wireless internet and airtunes. I connected everything and ran the airport utility. Everything is good, so it says. I can play music through my stereo using airtunes, but when I try to get on the internet I get nothing. My macbook recognizes the network, but I can't load any pages. I've tried unhooking the ethernet from the express and unplugging the power from my modem, then plugging my modem back after about 30 seconds, then reconnecting the ethernet to the airport after another 30 seconds but still, nothing.
Does anyone know what I'm doing incorrectly? When I connect my macbook directly to the modem via ethernet I'm on the internet just fine. Thanks!!!!

Do you have the Express setup to distribute IP addresses?
If you do, you might turn it off in the Airport Utility.
Also check you IP address on your MacBook.
Make sure it is not self-assigned or something different than what your provider (cable modem) usually assigns you...

What is the best setup for cable modems/routers for mac?

I use a MacBook Air and currently have CableOne as my ISP. I use the AirportExpress for my router. To upgrade to faster speeds I need to upgrade my modem. Am thinking about using a modem/router combination. What is the best set up for me?
Do modem/combos work well with Mac?
Also - would it be better to upgrade to an Airport Extreme? We had a housefull of Mac people for Christmas and the Airport Express couldn't handle all the devices very well at all.
Your wisdom is appreciated. Thanks.
Dave Weitz

By the way, CableOne lists mainly Motorola modems and combos as supported equipment.
Thanks.

Help with extending the range of Motorola cable modem

After struggling with AT&T DSL (with slow speed and intermittent drops), I switched to Time Warner Cable, and now sport blazing-fast connection via Ethernet cable into my 27" iMac. They gave me a Motorola Surfboard sbg6850 wi-fi modem, but I'm finding the range of the wi-fi to be totally inadequate... I get drops and unreliable connections only 20 feet away with iPads and Macbooks. I want a pleasing dome of wi-fi all over my house!
Through other discussions on this board, I see that Airport Express is NOT compatible with the Surfboard, a fact which surprised and disappointed me. What are my options for extending the wi-fi range?
—Could I buy a non-Apple product (router) to extend the wireless range? Can it be managed from a Mac?
—Could I connect an Airport Extreme to the Surfboard via Ethernet cable, and use the Airport Extreme as the router to extend the network via Airport Express?
—Could I use the Airport card in the ethernet-connected computer (in this case, a 27" iMac) to create a network that COULD be extended via Airport Express? (I'm using it now to share the Internet, rather than connecting directly to the Surfboard, but when the iMac sleeps, the network is unavailable.)
There's got to be a way...

Since you went with your option 2, you basically have the fundamentals for a roaming network as both routers are interconnected by Ethernet. This also means that the 802.11n AirPort Extreme Base Station (AEBSn) should be reconfigured as a bridge, i.e., Connection Sharing = Off (Bridge Mode) in AirPort Utility (v5.x). This would allow the TW combination cable modem / wireless router (or gateway) to provide both NAT & DHCP services for the entire network.
Now with the AEBSn configured as a bridge, you can add the 802.11n AirPort Express Base Stations (AXn), via a wireless connection to the AEBSn, in an extended network configuration. Note: The extended network works in a "wheel" like fashion with the extended base station at the hub of the wheel. Each extending base station would be spokes on that same wheel ... so how successful you will be extending the wireless network will be based on proper placement of each of the extending stations for full coverage. Please take a look at the following AirPort User Tip for proper placement details.
The other thing to take into account is the potential Wi-Fi interference between the TW wireless gateway and the AEBSn. Either disable the gateway's wireless radio, or be sure to allow for sufficient radio channel separation between radios on the same band.

Bridge an AirPort Express from an Extreme connected to a Motorola DOCSIS 3 cable/modem/gateway via an ethernet cable? Can I connect ethernet to the Express to setup/handshake/coordinate, and then unplug the ethernet cable from the Express?

In other words, does the AirPort Extreme NEED to be the device connected to the coaxial cable, or can I connect that cable to the Motorola SBG6580 DOCSIS 3.0 cable modem/wireless gateway? (My Internet provider requires DOCSIS 3.0 for speeds above 12 megabits/sec.)
Will the Airport Extreme "program" the Express via an ethernet cable, and than the cable can be removed?
The "bridge" or "repeater needs to be quite a distance away from the physically connected cable modem/wireless gateway and the ethernet- connected AirPort Extreme, and we have wall-to-wall carpeting, and the walls and ceilings are off-limits (family politics), so a looooong ethernet cable is out of the question.
Any help is GREATLY appreciated!
Thanx!
P.S. The 802.11 in my house (ground floor, about fifty feet away from the modem; in the living room about 35ft away *****! And Motorola touts this wireless gateway as having amazing coverage (360, I think they call it),but in fairness, this house is old and has a 5 hanset cordless landline and a microwave and a fan, etc., etc., etc......

See if find a solution in one of these discussions:

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.

Messages port forwarding Telstra cable modem

Anyone know how to get Messages video chat to work with the new "BigPond Ultimate Cable Home Network Gateway". It's the Netgear CG3100D-2BPAUS.
Messages worked just fine using the old Motorola cable modem but stopped with the new one. I've tried setting up port forwarding as per:
http://support.apple.com/kb/HT1507
and: http://portforward.com/networking/static-Mac10.4.htm
but no luck.
Thanks

HI,
Does this device (and the firmware on it) have UPnP ?
UPnP allows multiple devices use the same ports (Port Forwarding does not)
This means you can leave the modem/router doing DHCP to Issue IP addresses and it will not matter if the computer gets a new IP now and then.
In a one computer set up it is likely to always get the same IP when you start it up.
1) because you probably restart it before the lease time runs out
2) because there is nothing else to "take" the number.
However with Smart Phones, Games Consoles and multiple computers you may find that with out setting up IP address that don't change, either by Static routing or Address reservation that computers (And other devices) will swap IP addresses and set ups like Port Forwarding will not work - they tend to list which IP to send stuff to.
The Port Forward site lists only a CG3100 (plain, no suffixes)
Presumably you have used the info on the Port Forwarding bit to learn the access User ID and Password.
I linked to the AIM talk set up (Portforward.com > Chose Brand > Chose Model > dismiss advert page > chose App > set up instructions)
Using the link at the bottom to see the Router's screen Shots I went to the Basic set up one
http://screenshots.portforward.com/routers/Netgear/CG3100/Basic_Settings.htm
Near the bottom of the menu is UPnP
On most Netgears it is enabled by default. Specific Screen Shot.
On some devices setting up Port Forwarding or Port Triggering and having UPnP on can cause conflicts.
UPnP is needed for Screen Sharing in Messages or iChat.

Lost connection to my cable modem

Ok people I am hoping that you can help me out here. Yesterday my Time Capsule stop connecting to the internet through the cable modem. Called Comcast assuming it was there service. After an extensive check process we determined that service and the cable modem were working correctly. So then i proceeded to call Apple Support. Again through the check process of all the peices that are connected to finally determine that the TC was the culprit. I took the TC back to the Apple Store and they graciously exchanged it out. I took it back home hooked it up and it we are back to where I started, the new TC is responding exactly like the old unit. So my cable modem is a Motorala SB6141 and I have sevice through Comcast. The cable modem and TC have been working together for 6 months before this happened, with no new hardware added in the last three months. The cable modem when connected to the computer (Mac or Windows) directly can connect to the internet. I even tried connecting the cable modem to a AirPort Express and it had the same effect as the TC. So does anybody have any suggestions?

The SB6141 is problematic with the Airport routers.
There is some issue of compatibility.. it is hard to figure out.
If you replace the cable modem with a different one it will be more likely to work. I am not in the US so just look at posts about the more compatible models. Or simply use another brand router, and set the TC in bridge and use it as wireless and backup target.
I do think you can get some improvement in some cases using a crossover cable. I have made that recommendation and it has worked for people.
Or a small 10/100 switch between the two .. cable modem and TC.
https://discussions.apple.com/message/23236139?ac_cid=tw123456#23236139
You need to power cycle the modem whenever you change router.. I am guessing you are doing that.. but just to be sure.. at least 15-30min is required with some ISP.. 5min for others.. some are much longer..
The ISP must drop your previously connected equipment to pick up the new one.

Slow Cable Modems - Everyone Please Read

I am a Broadcom employee. Broadcom makes cable modem chipsets. Some of these chipsets have a slight design flaw. I am not at liberty to divulge any technical details. However, I can tell you that using a cable modem containing one of these chipsets with your Mac will result in slow internet speeds. Apple is not at fault. I'm sorry to say that fixing these design flaws, which only affect Mac users is not a priority at this time.
I am a Mac user myself and am just as frustrated as you are with incompatible products. This is why I am coming forward and informing you of this problem with our products. Our chipsets are used in almost all of the most popular cable modems. I am including a partial list of the most recent and popular cable modems that use our chipsets which have this problem. I am unable to find any information about older and less popular cable modems. Please understand that I can not and will not divulge any more information. Thank you.
All Linksys Cable Modems
All Motorola Cable Modems except for the SB5120
All Scientific Atlanta Cable Modems

Maybe Broadcom can answer the question as to why the Cable modems are slower with Macs with cable modems that do not have TurboDOX.
I have spent hours on numerous forums reading many users complaints and many users solutions from changing DNS to using certain modems.
What I have found is this. All and EVERY cable modem that people have references as working at full speeds on a Mac had 1 thing in common. This 1 this is TurboDOX. I have just completed about four locations where the Macs were slow with Comcast Cable modems. The latest being today with a new installation with a new SB5101 modem. I had the client go and buy a new SB5120 instead. The speed with the 5101 was 2-3Mbps and the speed with the 5120 was 18Mbps!!! yes, 18.
So the question is Why does TurboDOX make a difference with the Mac and not the PC????
Also, another thing to note is that some routers cap the WAN to LAN interface at 6Mbps. For example, the COMSUMER grade Netgear routers (usually the silver plastic ones) are capped at 6, however the Business class routers have varying WAN to LAN speeds ranging from 15Mbps to over 50Mbps.
Our setups for residential clients include either the Netgear FVS114P or the FWG114P VPN Firewall Routers. I have had no issues with Macs being slow with either of these routers and a Motorola SB5120.
FWIW.
And about the Design Flaw theory, Why did this speed issue just start appearing recently? I saw a site test fine at 6Mbps when it first was installed then recently when we went back to do some work find it testing between 1-3Mbps. Just Odd.
