Re: Update 2wire/cisco/macbook wireless works great !

Working flawless for almost 1 year now. Dont waste your time with the 2wire to work on the wireless with your macbook!

Bridged my 2 wire and hooked up a  Cisco Linksys router Model: WRT120N. Perfect fit for me!!!!

Re: connection problem with my macbook pro

I have the same problems with my MacBook. I was going to contact AT&T, but after reading all of the posts here I see that would be a waste of my time. I am wireless but my roommate is not.   If I were to put my 2wire into bridge mode and use a different router to handle my wireless needs.  Would that affect my roommates computer which is directly connected to the AT&T modem?

You have got to be $#!**! me!

 

I have a 2Wire 2701HG-B and use Mac's. Originally had a Speedstream 5100 which was replaced with a 2Wire to resolve a speed inconsistency issue which turned out to be a bad profile/oversubscription problem, but that is another story.

 

I have just spent the last 10 days going round for round with AT&T technical support troubleshooting intermittent DSL service drops and now I find this thread (and an AT&T forum at that)! To date I have had numerous calls to both level 1 & 2 technical support, two new 2Wire 2701HG-B gateway devices, 4 onsite technicians whom have tested the line, placed the service on a new pair, swapped ports at the CO 3 times, installed a splitter in the NID, replaced all connectors in the NID, ran the 2wire outside connected directly to the NID and witnessed the drops, all to no avail. I installed a 'home run' to the NID, installed a dedicated DSL wall jack (last AT&T tech replaced the CAT5 run and wall jack). I spent numerous hours trying different combinations of modem locations (RF/EMI?), changing every conceivable cable, nothing worked.

 

So, after reading this thread I place the 2Wire in bridge mode, turn off the wireless and use an Airport Extreme as the router/PPOE dialer/WAP. It has worked flawlessly for the past 12 hours, not single drop.

 

Why is this potential issue not documented in a knowledge base article that tier 1 (and above) technical support has access to? And more importantly, why is AT&T not working with 2Wire to update the 2701HG-B firmware to resolve the issue?

 

Unbelievable.

Re: connection problem with my macbook pro

I was having the exact same problems as posted by multiple subscribers on 8 pages here. I have a MacBook Pro and we have two other Macs (one iMac, one PowerMac G4 MDD, both hardwired).  The hardwired Macs would have occasional problems, but the MacBook Pro went offline CONSTANTLY. We tried several 'fixes' mentioned here and on the Apple forums -- moved the 2Wire up onto a wooden shelf near the ceiling in the center of the house, changed the wireless mode and channels, changed the security setting from WEP to WPA, cleared cache/cookies, called ATT a couple of times for line tests, etc.  Since we have no landline, lack of a DSL filter was not an issue.  After reading posts here and at Apple, we knew better than to engage in the futility and inconvenience of calling an ATT tech out to the house or have any of the hardware or wiring replaced.  

 

Nothing worked to stop the CONSTANT dropped DSL/Internet connections on the MacBook Pro until, last Sunday, I successfully bridged the 2Wire and hooked up a D-Link DIR-655 router.  I did call an AT&T Mac tech to walk me through the bridging process, and called a D-Link rep to walk me through configuring the DIR-655 router.  For some reason, I did have to reset my PPPoE password then reboot both routers and all computers as a final step.  It's been five days and I've only received one "you are not connected to the Internet" message that resolved instantly with a browser page refresh. I have lower-tier ATT DSL so sometimes it's a tad slow, and occasionally the connection hangs up for a second or two, but I've experienced NOTHING like the COMPLETELY DROPPED DSL/Internet connections MULTIPLE times per HOUR every single DAY since SEPTEMBER.

 

I found these websites to be helpful in this process:

 

2Wire Bridge Mode instructions (ATT tech followed this script word for word):

http://support.2wire.com/?page=view&article=22&text=bridge&cat=&sort=

 

Configuring the third-party router:

http://www.dslreports.com/forum/r24325019-2wire-with-external-router-process-

 

Thanks to the ATT subscribers on this forum, I can enjoy my MacBook Pro again and we don't have to consider going back to terrible TWC High-Speed (an even worse experience, if you can believe it, with no fix).

I have the SAME problem with my brand new macbook pro making the DSL DROP CONNECTION SOMETIMES EVERY 15 MINUTES IT MAKES ME WANT TO DO BAD THINGS.

 

Haha i registered on this forum in 2003!

 

ATT Should give me a router that is compatible with my computer. Wasn't i forced to buy this piece of crap. Thanks ATT i really appreciate it.

 

8 Pages of people with issues, yet you continue to SHIP this router and tell people to do the same stupid fixes. Does ATT realize how much money they are losing to service calls? Calling service techs out for an issue for 1000's of houses when the real issue is a piece of junk router. Its absolutely fraudulent they wont even acknowledge a problem exist.

 

Not one of ATT's higher management must use 1. Consumer DSL 2. Macbook Pro

att please stop. just stop it with these routers. you're just making people mad.

 

its obvious you signed some contract with 2wire to buy all their horrible routers and resell them to us.

the company does not want to admit there is a problem, at least as long as the guy who accepted the 2wire contract is in charge. because if there is a problem admitted then:

a) that person is directly responsible for the hundreds of thousands of dollars lost in service calls and tech visits when the actual problem is simply a faulty router

b) they will have to confront 2wire about this problem, harming their business relationship, since 2wire wont get all our money any more without doing something, or break contract...basically it would be a legal pain in the ....

c) admitting there is a problem means they would have to replace all our routers

d) what would they do with all the warehouses of these horrible routers

e) more i could think of

 

all of these things are a big hassle. i can pretty much guarantee that somewhere they are aware of all our issues and scuffing it off is somehow rationalized to be the most cost effective solution when it comes to job security for the people at fault.

Re: connection problem with my macbook pro

New to the forum... I just started having problems with this modem in February... the usual blinking green followed by the blinking red... the kicker for me is that the blinking usually starts after I quit out of a browser.  Google Chrome, Firefox, and Camino all seem to cause this modem problems, which is odd because as I said, they didn't really start until February... it's a shame that I'd have to buy another router and use this modem as a bridge in order to get the service that I'm paying for... it's ridiculous that AT & T is going out of their way to try and absolve 2Wire of any and all responsibility for this issue... they've got us checking our wall connections, line connections, looking for other electronics in the area "that might cause a disturbance" (really, AT & T?  It's 2011, not 1994) with the modem, making sure that the computer is at least 10 feet away from the modem... all of this running around in circles is absurd...

Re: connection problem with my macbook pro

Hooooray!

 

After only one week with my new MacBook I was going crazy, I almost returned it.  

 

I followed the advice of some in this thread and bridged my 2Wire and bought a $49 Netgear N300.

 

Fantastic! it took me about an hour and now have excellent service.  I am of course bothered the my AT&T hardware wound not work, but I am surfing again.

 

Thanks for the excellent advice!

Re: connection problem with my macbook pro

I have ran across this issue a few times myself, as well as some of the Mac users here. 

 

A few things that may/may not help.

 

Network name of the Mac-  Apparently some 2wires freak out because the network name (machine name) isn't proper or uses non-standard characters. This apparently drives the 2wire nuts.

 

Changing the base IP address from a 192.168.x.x to say a 172.16.0.x or another base address- Apparently someone I worked with a while ago found that his Mac was arp'ing the (&^$%*(%&*$) out of the base address causing the 2wire to shut down/reboot because the 2wire think's it was being attacked.  I never did find out which version of the O/S that was but one clue we did discover is the 2wire was reporting a attack from an internal address in it's logs.He did open up a Genius Bar ticket on this and he would e-mail me back if he ever got an answer as to why, but so far I haven't gotten anything back.

 

Change the 2wire's wireless channel- Most 2wires come on a default  channel 6. If there is other more powerful devices on those channels it might be just be plain wireless noise. Now for windows there is a utility called "netstumbler" you can run and see what channels are occupied. The idea here is simple, find the channel not showing up and use that one.

 

Watch the number of ports that are open- Had another instance where the Mac was opening up too many ports on the 2wire and the 2wire would just reboot and drop the connection. This one happend on wireless as well as wired.

 

 

Again keep in mind these are tips that may/may not help.

Re: connection problem with my macbook pro

David, thank you for the insight.

 

I had a feeling it had something to do with ARP packets maybe.

 

I will try to change the subnet ip range, and report back if it works.

 

Also regarding the too many ports open problem, im not sure how to fix that one besides enabling the mac firewall?

not sure on the ports one either. THat one can happen to windows and MAC machines none the less. We call it the bit-torrent kill of the 2wire as typically it would max out the connection table in the 2wire as well as max ports open. This too will cause the 2wire to reboot/disconnect. Now the 2wire keeps the connection count to 2048 I believe. My thought is what on earth are you doing with 2048 connections to begin with? The MAC firewall might not be a bad idea as you can get a first hand look at what ports are going in and out. I would also make them match to the 2wire's interface as well. Least if the 2wire "knows its coming" the 2wire already has it enabled.

 

The ARP packets didn't make sense till that guy tried another old linksys he had and it was choking that one out as well. Ironically all the windows based machines were fine (go figure!).

 

I am not sure and I haven't seen it anywhere, where the 2wire handles uPnP connections. When I saw the interfaces I can't say I saw it on a particular page, however the 2wire may just handle it and not report it.

Re: connection problem with my macbook pro

I changed the network to 172.16.x.x.

 

This has seemed to have fixed the problem, after a day of dhcp issues and what seemed like the same problem as before.

 

But today its been rock solid. I changed back everything to default basically with g connectivity, with wpa2 and have had my vpn connected, and its been solid even going on some video chat sites that would reset the connection many times.

 

TO ANYONE HAVING ISSUES TRY AND CHANGE THE SUBNET IP RANGE TO 172.16.X.X

 

Thank you again, David! If this is in fact not the solution I will of course post again, but obviously I'm impressed enough to make this posting.
