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.

My 3000H will no longer connect to the internet via my cable modem - help please.

I have 3 computers and a media server on a Linksys router with a Comcast cable modem. Everything AOK. 3 weeks ago my Lenovo 3000H shut down and rebooted for no reason. Then I began getting popups while I was on the internet saying that I needed to click on a button to make a dial-up connection. I would hit X or Cancel to make it go away. It happend more frequently and other related popups started, but I could close them and continue normally. Last weekend It happened again but I lost my connection to the internet and it would not reconnect. Now I get a big error message "Connecting through Wan Miniport(PPPOE)... Error 815: The broadband netowrk connection could not be established on your computer because the remote server is not responding. This could be caused by and invalid value for the "Service Name" field for this connection. Please contact your ISP and inquire about the correct value for this field and update it in the Connection Properties..
I called Comcast. They don't have a clue what Error 815 is. I have changed every cable, rebooted the modem, router and all computers countless times, and reset the modem per Comcast. I have taken the router out and connected directly into the Lenovo. I have gone through every screen related to broadband connection to no avail although, being a beginner, I see screens that I have no clue what they do.I have a couple of friends and a Comcast fellow who tried to walk me through the steps they thought would restore my connectio. No luck.
Can anyone walk me through the necessary steps to get me back to ground zero and then through the steps to reestablish my broadband connection?
Help Please?

Emma-
In Safari, press on the Bookmarks icon and select History. Then press on Clear History at the top of that menu, and see it there is any improvement.
If not, try unplugging your WiFi router for a few seconds. Then reset the iPad's network. Go to Settings-General-Reset-Reset Network Settings. You will need to reconnect the iPad to WiFi.

Cable modem issue/adobe reader issue

1. I have a PB G3 (bronze keyboard) and cannot connect to the internet using a comcast cable modem. BUT if I route the modem thru a wireless router and then plug my ethernet into that I have no problems what-so-ever. The big question is WHY? I would like to ditch the wireless router, if possible.
2. I cannot download Adober Reader 5.0 to my computer. I am running OS 9.2.2 it says it has downloaded and then when I go to install it gets part way through and then stops, doesn't say anything but doesn't continue downloading....

Megan,
Welcome to the Discussions!
If the file has downloaded successfully to your desktop or wherever you have designated your download folder, you should see a file named 'rdrweb.sit'. Double-click on it to decompress and you should see an icon named Acrobat Reader Installer. Now quit all applications, restart while pressing the shift key and release when you see 'extensions off' under the Mac logo. Find the Acrobat Installer and double-click on it to install. You may have an extension conflict preventing the installation...just restart when done.
If you still have a problem, find all versions, if any, of Acrobat Reader already installed, drag them to the trash, then try the install again.
If still having problems, run Disk First Aid and also rebuild your desktop file:

Regarding the cable modem - what are your settings for:
AppleTalk (should be set to Ethernet)
TCP/IP (should be set to Ethernet and Using DHCP Server)
The above settings are what some DSL and cable modem companies use. Give it a try; if unsuccessful, call Comcast.

Fair enough the battery is an issue. Never realy thought about that. Hopefully when the new long lasting batteries that we've been seeing in the process of production are available i believe this is a must. Yes the platform is amazing at the moment with complete support to 3rd party apps which is the best thing about them, but theyre slightly less good looking. And getting more and more ugly. They need a lil more effort put into design, of product and software. For example the slider on the n95 8gb, might be better than the vanilla n95 but no where as near as the lg shine or even the w810i which is half its price. All the buttons on the front of the phne ie the menu etc all creak when i press them. this phone cost me £400. Its got the build quality of a £50 handset. so ive sacrificed on build quality so give me more once ive turned the phone on. I think what has habbened is us consumers have started to settle for less. Everything is possible but Nokia seam to be raising their prices quiker than there technology and we keep falling to there products like slaves. Just look at the profit they made in the last quater of 07. Surely this is a multi billion £ company with soaring profits, and why. Because consumers starting to settle for less and pay more for less. If this handset came out at £600, or even £800. I wouldnt lie to you, i would still buy it. Its an amazing phone. But as to what we getting for the price its still a little bit behind in inovation. If we continue to support this extortionate increase in prices and consumers still complaining bout things that could make it better where does this end. Its about time we got exactly what we pay for and Nokia start to concentrate more on what customers whant to see in their next handset before the start making it. Give us what we want, Ask us what we want, And then put a price tag on it in and we'll pay whatever. Because it is exaxtly what we want.

Intel Modem Users please read

There's an issue with Intel Modem drivers that's holding up the 2.6.16 kernel release, as explained by tpowa here. If you're using either of these drivers, please post here, to give him an idea of the numbers involved.

Yeah, I'm on the mailing list. I'm just concerned about the whole "NO NON-GPL!!!!!!!" thing. I don't use a hell of a lot of non-free, but the idea of simply refusing to allow them is badbadbad imo. But then, I'm not RMS.
Well, GPL is by design incompatible to anything else.
I won't post an opinion now, since I don't have that modem anyway.

Everyone please read and help me with this...

ok so about a year ago i installed iTunes on my computer and had a couple hundred songs downloaded. about half of them were bought out of iTunes. I had them all onto my iPod nano. Then a few weeks later my computer crashed. The hard drive "died" as you can call it. I have recently bought a new computer with Windows XP and we will soon be getting an upgrade to Vista.
I have two questions...
1). does anyone remember about the online live support we used to get from live apple representatives? it was instant messaging with the representatvies and they would help you with your problems. Does anyone know if that still exists? and if it does could you please give me a link to that site?
2). Is there any possible way for me to take the songs i have on my iPod and put them into my new library?
please everyone i need all the help i can get...ive lately been playing all my songs from a speaker system i bought that would connect with my iPod...i would like them to be on my computer...

Time warner cable modem

I am having trouble setting up my wifi with the Arris Time warner Cable Modem. I can get connectivity to the wifi, but it doesnt stay connected and the wifi light on the modem turns off. To set up the wifi i went to this cite: http://192.168.0.1/
I thought following steps on the cite would solve my problem, but again, I dont know how to keep it connected. PLEASE HELP
I'm not that tech savy so i sont know what alot of the acronyms mean

WiFi via cable company modems normally is not that good. I would get an Apple Airport to simplify matters. At least then you can use Apple's own software that has easy to go through steps. Just remember to plug in your airport to the WAN port when connecting to LAN port of the cable modem via ethernet.

Wireless router without a cable modem

Can this be done? Where i live i dont have access to a cable modem but i would still like to have a wrieless net work in my house, any sugestions?

ok, last time i tried to install a router it would not let me install it without a cable modem, so a router like the WRT610N would do what i need it to do as far as being able to install it without a cable modem correct?

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!

NTL/Virgin Cable Modem trouble... Need help please...

Hello,
I am a new NTL user, meaning I got the confirmation letter from NTL and then when they came to install it, the entire package turned into Virgin. They promised me a 10mb line which they say I have and a week into my TV and broadband cable modem experience, they dropped the Sky Channels. I wasn't too happy about that. But I wouldn't mind so much if only my internet was as stable as they said it would be.
I am new to Cable Modems and I have always had ADSL, which I think is much more stable compared to my cable modem.
I have a supposed 10MB line and a little blue box with a strange thick wire going into it and an ethernet cable going out of it into my new Airport Extreme (Flat one).
My problem is this, aside from the fact that I constantly have drop outs and sometimes complete loss of signal, the Airport is in a fixed place no more than 3 meters from my MacMini Core Duo.
I also don't think I have a steady 10MB line, cause when I try to download files from Apple or their trailers, it is VERY slow. I came from a 4MB ADSL and it was REALY FAST! So why is Cable slower?
Am I doing something wrong here? The entire set up from Virgin was more or less non existent and they didn't help much on the phone.
How can I have a more stable line and get at least 4 MBs out of the 10MBs they claim I have....
It jumps high during a download and a few seconds later it drops to the point it simply isn't worth it...
I would appreciate any info you could give.
Here is my set up : Apple Airport Extreme Control Panel

PS. the NTL Modem is called NTL 250 that is all it is a tiny blue modem of sorts...
I am on a MacMini Core Duo which version of Airport card is in it I don't know and don't even know where to look for the info on it. But All I do know is that I often experience drops in my signal and sometimes a total loss of connection...
Thanks

Hi.
I've been a Telewest - now also Virgin Media customer for many years, and have been using their 10mb connection for over a year now ( are you aware that in May they're upping it to 20mb)
The speed of the connection is quite erratic, but for me has improved since xmas.
Here is a site that will check your speed, if you still have problems, call them up, and even though they're not very Mac friendly, insist that they come round and check it.

By the way, I called them when they lost Sky, and threatened to leave - they gave me a 20 quid/month discount - give it a go!

IBook and Comcast Cable modem--can't connect to Internet? Please help

Hello everyone!
I have an ancient iBook . Here are the stats:Mac OSX version 10.0.3(told you it was ancient), 193MB, PowerPC G3. I bought it off of eBay about two in half years ago and it didn't come with an Airport card...I only received a laptop, the original box, some cds, and the adapter. I have a Comcast cable modem and I was wondering if anyone could help me figure out how to connect my iBook with the modem. Prior to Comcast, I had Bellsouth and all I had to do was simply unplug one end from my mother's Dell and plug it into my iBook and it instantly connected. However, I can't do it with the Comcast. Can anyone tell me how? Pretty please?
iBook Mac OS X (10.0.x) PowerPC G3, 193MB

You likely need to contact Comcast to get them to help you set up the iBook for your new cable internet service. They should be able to walk you through it.
In case it may be an encryption problem, you may want to check out iFelix's post in this thread:

Cable modem link slowness w ISA570 and CLI "show tech" equivalent

Hi, I'm helping out a non profit that has a Mediacom 100mbs link, they get 90+ Speed connected directly to the cable modem, but anywhere past the ISA570 they only get 50-60mbs. They have switched cables, added a separate port, tried different PCs, results are the same, 50-60 mbs max.
Also it's their understanding the ISA570 can't do CLI, so how can they get the equivalent of a 'show tech' command to a file to send offsite for troubleshooting,
Thanks.
Jim

Hello,
There is something similar to show tech on the ISA.
Log into the web GUI, go to Device Management >> Cisco Services & Support >> Send Diagnostics. At the bottom of that page is a Download button that will collect the config file, the logs, and some debug outputs into a zip file. You can use this to troubleshoot the device, although I usually prefer to be on the live device itself to look at things.
Before you dig too deep into those however, what kind of security services do you currently have enabled on the ISA? I was looking over the datasheet and while the SPI is capable of ~500mbps, when you start to enable the various security services those speeds start to drop.
If we look at the UTM (Unified Threat Management) throughput measures, that is at about 75mbps, which is fairly close to what you are getting. I would go through and disable the various security services one at a time and test your speed. My guess would be either A/V or IPS is slowing your connection down. It may be one or a combination of these services causing the slowdown. You can disable those options, or just explain that the extra security will cost a bit of speed.
Hope that helps a bit,

Please help, I can't figure out how to use the cable modem...

I'm visiting my sister in Baltimore, Maryland for about 3 weeks, and I want to set up the internet on my macbook so i don't have to keep using her powerbook g4. She has a Motorola Comcast Cable Modem set up for her powerbook, but I can't figure out how to find the info about her connection so I can copy it down into my computer. I keep going to her system preferences section and clicking the network button, but none of the various internet connections shown are actually the one she uses to connect. Please tell me where I can find her cable provider's info in her powerbook and where, in my macbook, i can enter this information and get on the internet.
p.s. i don't know if this is necessary info, but with the motorola cable modem came an installation disk for if you wanted to use the usb drive cord instead, but that disk isn't even read properly in my macbook. like, it lets me open up the disk and see all the files on it but it doesn't automatically start up an installation wizard so i really have no way of installing the items on the disk.

well, i can't really tell if i am only allowed one connection with this isp. basically, whenever i plug in the ethernet cord, all of the information gets filled in in the ethernet section of the network, except for the router info. there is router info filled in on my sister's computer whenever i plug the cord into her computer, though. does that mean i can't also use the modem for my computer? sorry, this is both my first time using a mac and my first time using anything other than dial-up, so i'm pretty lost. thanks for the info you've given me thus far.

Please help me connect eMac, cable modem, and Airport Extreme Base Station

I connected Ethernet cord from cable modem to Airport Extreme Base Station and then another Ethernet cord from Airport Extreme Base Station to eMac, but I could not get internet access on my eMac that way. I'm only getting internet access by directly connecting eMac to cable modem. Can someone please help me with a step by step explanation of how to set these 3 machines up so that I can have internet access on both my eMac and, wirelessly, on my new MacBook. Thank you very much in advance.

jenngee, Welcome to the discussion area!
Ensure that you power off the cable modem for a minute or so when you switch it to another Ethernet device.
Ensure that you are connecting the WAN port of the AirPort Extreme base station (AEBS) to the cable modem. The eMac should connect to the LAN port.
The steps for setting this up can be found in the "Designing AirPort Networks" (direct PDF link) document. Look through that document and try to get it setup. Then return here if you have more questions. Don't forget to post what you tried and the issues you encountered.

I cannot retrieve the password for the wifi connection on my imac and so cannot access the internet with my ipad at home. I have a cable modem. Help please!

If you mean that you cannot remember the password for your WiFi network this will work for you - or it should work if you are the administrator on the Mac.
You will need to be logged in as the administrator on your Mac and you must know the password - Open Keychain Access on your Mac in the utilities folder, click on Passwords. Find the Airport Network Password listed on the right. Double click on it. Click on show password in the the window that pops up. Enter your administrator password when prompted and click allow.
If Keychain is locked - you must enter the administrator password there as well to unlock it and access the password.
If you have set the Mac up for Internet Sharing for the iPad to share the Mac's connection, just create a new network On the Mac with Internet sharing and a new password.
