Question: Will it hook up AT&T DSL Internet service
Document: I have AT&T DSL and I bought this to reduce the number of devices on my counter. This is a modem and wireless router in one. It works very well, the only issue I had with setting it up is that I needed a special password from AT&T to allow the internet to pass through it. Their customer service was very helpful and was quickly able to help me get online.
I am contemplating a switch from AT&T DSL Internet to Comcast. AT&T speed is less than 5Mbps and Comcast offers up to 30Mbps for nearly the same price. The "rub" is that I am reading some very negative reviews on the effort of new subscribers to avoid the $7.00 monthly charge for their modem. I own a Cisco-Linksys X2000 ADL+2 and cannot determine if this is compatible with Comcast service. In fact, I am not certain of the protocol of Comcast service.
I lived with this thinking that the cause of the connection dropping was my rural location - my speed tests showed quite a bit of latency and other indicators that my connection with the DSL switch was sub-par. My connection was also very slow - rarely would I see download speeds in excess of 50KBps per second and typical download speeds were about 30KBps. Again, I lived with this because AT&T; DSL is the only broadband service available in my area that doesn't cost $100 per month or better. "Living with my problems" was quite silly - this simple upgrade costing less than $100 has fixed most of my problems.After one particularly bad day where I had to reset my modem six times in the period of about two hours, I broke down and bought this router from one of my local electronics stores.Install was a breeze - it took approximately fifteen minutes from unpacking to surfing the internet.
This product works greate with my AT&T DSL service. I had no problem setting it up using the Quick Setup feature. All my wireless and wired equipment works great. WII, IPOD, IPHONE, DROID RAZR, DISH Network Hopper, Laptops, Desktops etc..
Extremely easy setup, took maybe 5 minutes. I have AT&T; Elite 6MBPS DSL service, which is the best I can get from them without going to uverse. I was using their 2701 wireless gateway which worked fine on the wired part but sucked on the wireless. My son is a gamer and he hated it. Was constantly disconnecting and reconnecting on the wireless and the speeds you do get are slow. This thing has been perfect so far, I would recommend this. My Son says it is a million times better than the AT&T; gateway and he hasn't had any problems with the connection yet.
Bought this as an upgrade/replacement for an old Homeportal 1100 Modem with Linksys WRT54G router. After setup, had problems with the unit dropping the internet connection (not the wireless connection, just internet). Sometimes this would happen several times a day. Upgraded the firmware to the latest version, did not help. I had never had this problem with my original setup and equipment. I have a separate DSL filter (at entrance to my house) and phone line for my AT&T DSL line, so I know this was not the problem.
After a couple of months of dealing with this problem, I RMA'd the unit back to Cisco/Linksys. Waiting to see if the unit they return will be any better. I need a reliable internet connect for my business, so I purchased a separate Netgear modem and wireless router. This system has been operating now for several weeks with no dropped internet connection. Again, proof that the problem is not with AT&T or my DSL line/physical connections. There are lots of posts on the internet about the X2000 unit dropping internet, so I feel this is not an isolated problem.
You can try using the CD to install, but I had to call CenturyLink and just ask for my DSL settings. If it isn't obvious from the documentation just ask for the PPPoE username, the PPPoE password, the VPI, and the VCI. You can enter these values during CD installation process. Conveniently, the first sheet in the package has phone numbers for AT&T;, Verizon, and CenturyLink. Signal strength has been good, and I like the added features such as the USB Key creator for getting other people on easily and the parental controls for automatically limiting internet use hours and restricting questionable sites.
At the time of writing this review, I have been using the router for approximately two weeks.In summary, the X2000 router is a great piece of equipment for homeowners with DSL or cable internet.I personally have been using AT&T; DSL for about two years now. I live in a rural area where AT&T; DSL is the only reasonably priced broadband internet available. I fought and fought with my old DSL modem (a Siemens 4100) as it would drop the connection a couple of times a day, necessitating a manual reset of the modem.
I bought this all in one networking device to replace an old Westell with the same basic features and functionality. It works ok with my AT&T; DSL no problem and speeds are not in issue. But the wireless radio on this device is not very powerful. The old device covered my whole house and part of my yard no problem but this one not so much.As soon as you leave the room that it is in the signal really fades, to the extent that I thought it was defective and spent a few hours with Cisco/Linksys customer support troubleshooting it to no avail.
Answer: As far as I know it will hook up to any cable or dsl provider. I have Centurylink, but I  have also had it hooked up to Comcast cable without any problems.
