Got Charter internet service the other day, Express package (15mpbs). My current Linksys modem evidently is not compatible for that speed. So I need a new modem.

I was looking at getting the Motorola SB6121 SURFboard for my modem.

I currently have a Linksys WRT54G router. Am I going to need to replace this also? Or is this going to be acceptable to use for now? I don't have to have blazing fast speeds. But I don't want to be paying for 15mpbs and only getting half of that due to my router. So I was curious if anyone knew how my router would effect my speeds.

Are the modem/router combos such as the Motorola SURFboard Gateway SBG6580 reliable? Or is it better to keep the modem and router separate?

You should be fine with the WRT54g router.

I agree with Mike, the router should be fine. My experience with SB6121 hasn't been that good. It gets a lot of 'Lost MDD timeout' errors and the speed goes below 1mbps (20mbps connection) and needs resetting every 3-4 days. A lot of people have reported on the internet about having the same issue. My provider Comcast wouldn't help much since 'it is your modem'. I am going to throw the SB6121 away and going back to renting Comcast modem as then 'it is their modem' and their problem. And yes,it is better to keep the modem and the router seperate if you have the space and do not mind having two boxes and the wires between them. This model helps you upgrade/replace each one seperately when needed, which is more cost effective.

Thanks to everyone for the information. I'll stick with the WRT54G for now and plan to upgrade the router in the future.

So the SB6121 has some issues? It appeared to be very highly rated based on reviews, etc. Thanks for sharing, that is good to know. Is there another modem that anyone recommends?

Yes,the SB6121 has very good rating. I am not necessarily saying that it is a bad modem. It could be some signal compatibility thing that the provider could easily fix by changing some configuration from their end. But like I said 'it is your modem'. Google 'Lost MDD Timeout' to see the discussion about this issue on SB6120/SB6121.

Ionel,
Contact your internet provider and ask them. Without knowing what type of internet service you have (or will have) no one can answer this. If you are using the traditional ISP service method (cable, dsl, sat) you will certainly need a modem as well. If you are currently getting internet service and you have the ISP supplied modem then any basic WiFi router will connect to that modem.

Then buy any WiFi router you wish, wire (ethernet) from your ISP supplied modem to the new router. You are done. :)
Simply connect all network devices to that new router.

Kathy,
Need a bit more info to help. :)
Do you currently have high speed internet service in your home? Do you have a WiFi router but you just don't know how to connect to it? Or are you looking to buy your first WiFi router to connect to your current ISP supplied modem?

Just to update you guys. Looks like my problem was with Comcast's signal strength (even though they kept saying its excellent). Looks like the only fault of the SB612x is being a little too sensitive to signal level compared to other modems. I found a posting from last week on the discussion forums, where this person accidentally found that his SB612x problem went away when the Comcast tech added a 6dB attenuator to the line after noticing that his signal strength was too *high* (around 15dB on all 4 downstream channels). My signal had been around -15dB until my utility company pruned some tree branches in my neighborhood when it went to -9dB (do not know if they were related, but it was observed). I bought a 6dB attenuator but that worsened my problem (also my signal strength went back to -15dB) so I removed it. But then I also removed the splitter in the cable box and the signal strength went to 0dB which is where it should be. The modem has been rock solid since then. But I noticed that Comcast's signal spikes by about 7dB occassionally, kicking off a burst of codeword errors in the counters. But looks like I am still within tolerable range to cause any errors to be logged in the logs or to affect service. So if any of you is having the same problem, keep adding/deleting attenuators until the SB612x is happy.

I'm thinking of trying to set up for wireless printing from my iPhone. I have WiFi in my home. Besides a wireless printer, what other equipment or software will I need? I know that I can download an app for printing from the iPhone. Any help appreciated very much.
