Compatible? Modem and Router
Hi:
The Modem and Router Combo. I've been using for years is 'G' form that is 'non-fast' one, .... 54 Mbps. Now I want more speed, then I'm thinking of 'N' form, ... 150 Mbps Wireless Router while I plan to stay on the Modem, 'G/54.' My question is; Modem and Router got to be same speed, 'G' or 'N?' In the case I'd install Router 'N'/150 Mbps, what would it happen to the Modem that is 'G?' Tanks for your help in advance. |

In the case I'd install Router 'N'/150 Mbps, what would it happen to the Modem that is 'G?' Tanks for your help in advance. If it was my equipment, I'd connect the modem and router with wire, as they could be co-located. In some cases, you can buy a combination modem and router, so they're inside the same box anyway. That is the easiest way to solve your problem, is integrate the two of them together. /\ 150mbit/sec ~10mbit/sec /\ modem -------------- router_802.11n computer_#1 ethernet cable computer_#2 In the figure, either computer can talk to the modem, at 10 mbit/sec, which is limited by the connection to your ISP. So that path isn't particularly demanding of performance. If computer #1 wants to talk to computer #2, that can flow through the router. So the 802.11n may help you with file sharing for example, between computer #1 and #2. I don't know all the details of 802.11n, but I understand that "N" has some fallback procedures, if "G" equipment is detected. For example, "N" can use 40MHz channels, instead of the older 20MHz wide channels. If older "G" equipment is present, that may prevent the "N" equipment from using the wider channel setting. So if I was going to waste money on an upgrade, I'd want to make damn sure there was no legacy equipment in the vicinity, preventing me from getting full performance. I think "N" can use 2.4GHz and 5GHz, and it is possible there are fewer restrictions on 5GHz. That isn't clear in this powerpoint slide set. This slide set addresses "N" in the 2.4GHz band. https://mentor.ieee.org/802.11/dcn/0...esentation.ppt http://www.wireless-nets.com/resourc...te_80211n.html "The most effective configuration for mixed mode is to install two radios in each access point. Place the 802.11b/g traffic on 2.4GHz radios and the 802.11n-only traffic on the other (ideally 5GHz) radios. Keep in mind that not all countries allow 802.11n 5GHz operation." So if you're going to do it, read up on it first. Don't expect the instructions "on the back of the box", to be completely honest about how to install it. So if possible, I'd "wire" the modem to the router, and disable the radio on the modem. That way, the new wireless router could be a fancy "N" version. Then, you'd upgrade the interface cards on all the computers to "N" as well. Even if a wireless device has no controls over its radio, connecting a "terminator" in place of an antenna, will absorb all the radio energy. As long as the terminator plug has sufficient power handling, it can be used to make a radio "quiet". So if the modem had radio and wired interface, and no controls over which was used, there are ways to influence which interface it uses. I picked up a few hints on this stuff, here. http://www.smallnetbuilder.com/wireless They have charts, if you can figure out what they're measuring. http://www.smallnetbuilder.com/compo...ess/Itemid,200 A review of a router with both 2.4GHz and 5GHz radios. Also has very capable wired ports, such as the WAN one you could run over to your modem. http://www.smallnetbuilder.com/content/view/30925/96/ Paul |

Thanks for the detailed and knowledgeable response.
Sounds it's NOT easy to replace an existing router to the brand new one that is more 'speed' purchased from local Staple. The Staple tech. told me my IP is slow, because of non- 'Fiber Optic' or some similar phrase. His IP is much faster than my IP. He told me 'N' is very ideal to resolve this issue, .... slow. In my fear that if I'd replace brand new router/N by taking off the existing router,'G,' it sound like 'conflict' .... even not able to get Internet at all in some of PCs with XPs. I'm not even close to an expert to deal this form of issue. If that would happen, I might end up needing to call IP tech. to fix. Normally, IP tech shows up two or three days later after initial call. Also, all IP techs. have not good knowledge to deal with some of issues. One time, I needed to wait more than one week to resolve the TV issue when TV changed to 'digital.' That was after three different techs. and one of them found the right answer, ... wiring inside the house. Then, I might be better to stick with the current Modem/Router combo. which is 'G?' Any other suggestions in regard to 'speed-booster?' Thanks, "Paul" wrote in message ... MapleE. wrote: Hi: The Modem and Router Combo.

In the case I'd install Router 'N'/150 Mbps, what would it happen to the Modem that is 'G?' Tanks for your help in advance. You need to better understand the difference between a "modem" and a "wireless router." It's not the "modem" and the "router" which have to be the same speed, but rather the "wireless router" and the wireless adapter in your computer that have to be the same speed (otherwise, the wireless connection will only be as fast as the slowest device). You also should stop listening to Staples sales people. Buying a wireless-N router will do nothing to speed up a slow connection to your Internet Service Provider (ISP). Your Internet connection is only as fast as its slowest link. If your wireless router *AND* the wireless adapters in your computer are *BOTH* wireless N devices, you may get connection speeds between your modem/router and your computer of up to 130-160 Mbps. If the connection between you and your ISP is by dial-up, the maximum speed seen by your computer will be 56 kbps = 0.056 Mbps regardless of the speed of the connection between your modem/router and your computer. If this is what you have, you will see no difference by using wireless-N. If the connection between you and your ISP is DSL, you may get up to 1500 kbps = 1.5 Mbps, depending on what you are paying for. Some DSL service is slower. If this is what you have, you will see no difference by using wireless-N. If the connection between you and your ISP is cable, you typically will see about 6 Mbps. If this is what you have, you will see no difference by using wireless-N. If you pay extra for "premium" cable service, you may get up to about 30 Mbps. At the upper end of this range, you might see a slight improvement by changing from a wireless-G network to an all wireless-N network. I suspect, however, that the speed difference would not be noticeable in typical Internet surfing. If you pay even more for "ultra premium" cable service, you might get up to 100 Mpbs. In this case, you definitely would see a speed improvement if you replaced both your router and your computer's wireless adapters with wireless-N devices. If the connection between you and your ISP is by fiber optic cable to your home (e.g., Verizon FiOS), you can pay for either 15 Mbps, 25 Mpbs, or 50 Mbps. If you have the most expensive play, you will see a speed improvement by changing to all wireless-N devices. I expect that Verizon also will soon match "ultra" cable (for yet an additional fee) in those markets where cable is offering this service. -- Lem Apollo 11 - 40 years ago: http://www.nasa.gov/mission_pages/ap...0th/index.html |

Any other suggestions in regard to 'speed-booster?' Thanks, When you get your Internet connection from the ISP, they have different service plans. For example, my connection is via ADSL from the telephone company, and the transfer rate is 4 megabits/sec. If I had 802.11g, that would likely handle that rate, as long as the signal level was good and there weren't too many walls in the way and so on. Wireless setups hardly ever run at the rated speed, so for starters, you should assume they'll run at half the stated rate. Still, wireless-g should be able to handle the download speed of my ISP. There are some Verison FIOS plans for comparison here. They offer 15, 25, and 50 megabits/sec download rates. For the last two, I might want 802.11n equipment for distribution within the home. But if your ISP offers much slower service, like mine does, then 802.11g is probably good enough. http://www22.verizon.com/Residential...lans/Plans.htm Also, I don't use wireless, preferring wired connections with constant transmission capabilities and reliable performance. In ideal circumstances, wireless is fine. If you live in an apartment building, surrounded by tons of people with wireless, that might be a less than ideal environment, to get good performance.

Lem:
Thanks for the VERY knowledgeable and informative response. I really appreciate it. Since I learned by reading your response, I'm very sure I do not need an unnecessary trip to the stores along with 'hard-earned money' to spend. It's a pain for anyone like me who has a very minimum knowledge as to 'ISP' and all other necessary components my household needs. "Knowledge is POWER.'

Paul:
Thanks for the response. I live in big city and there are two 'big' ISPs that apper to be competetive. Before getting a current ISP, my household was on another ISP that is now 'fiber-optic,' that offers faster service according a Staple tech./sales associate whom I know for few years. Also, I live in house, not apartment, but like any big city, there is a tight space between neighbors. Mostr of neighbors have same ISP my household have and I see often ISP-truck driving around in my neighborhood. Then, I guess there are some issues like mine, but again my household a kind wants to stick with a current ISP. Becuase a rate is not bad and also some of tech guys are very proficient and friendly. My ISP offers both 'TV' and 'five PCs' service. Only an issue I have is a yound generation who likes 'speed.' By reading all of responses, I definitely learned a lot of stuff in regard to ISP and most importantly, 'speed.' btw) The way you're writing/response, I'm reminicense a name 'Paul.' His initial is 'PT' and my initial is 'GE' and worked together long time ago. That person, Paul loves computer more than his real job. But, I heard he moved away to the country and I changed a job. If you're that person I fondly remember, I want to say 'THANKS,' because you helped me a lot about 'PC' and all others. Thanks again, "Paul" wrote in message ...
