Wireless N-Router

anyone know if router is really improve speed of ISP?
and how it work.
I plan to buy one but still don't know which one is good

is this router worth to buy?
Newegg.com - NETGEAR WNDR4500-100NAS N900 Wireless Dual Band Gigabit Router IEEE 802.11a/b/g/n

 

I always buy D-Link products. Anything with 802.11n and gigabit ethernet will always suit you well. You can get a quality one anywhere from $50-100. I have the DGL-4500 and have had 0 problems with it.

 

Generally speaking the limiting factor will be your ISP connection speed, until you get well over 20Mb/s. The netgear routers are generally quite reliable, have good built in firmware, and be upgraded to Tomato, OpenWRT or DD-WRT. If you don't need dual band, the WND3500L is a great value and a good performer, with stock firmware or one of the above listed open source options.

 

Everyone has their favorite products, personally, i go for Linksys since their routers never failed me contrarily to D-Link. Not that D-Link has bad products only, just bad personal experience.

As said previously, a router won't increase the speed of the ISP, however a good router will give you a problem free network whereas a half decent router is likely to fail early and cause all sorts of problems like random disconnections, the need to power cycle it often etc.

If you have a very high bandwidth connection, in the 20mbps range, then a N router is a must, otherwise a good G router will do the trick as long as you're not streaming HD content on transferring files over the wireless network on a regular basis. I'd still go for a N router.

What will you be doing with your wireless network and how many devices do you plan to connect to it? I would also download a program called inSSIDer and check how many networks are in range of you. If there are a lot, then a simultaneous dual band router is a good idea, if there aren't many networks, a standard 2.4GHz router will do the trick.

 

So to consolidate on what everyone else alread said - a router wont make your ISP speeds faster UNLESS you are paying for faster speeds and have a crappy router, say paying for 50Mbps and only getting 20Mbps which is a limit of the old Linksys WRT54G routers. In that case upgrading your router will give you the full speeds you are paying for.

The other thing of crappy speeds could also be your ISP's connection to you. If the modem isn't getting a good speed, it can't send faster speed to the router you have, even if you have the best router in the world. So first make sure you get good speeds from your modem to figure out if the router is slowing it down or the modem is the issue.

 

You make a good point there in your last paragraph SHoTTa35; directly connecting to the ISPs' CPE/end-user device is a good way to test/troubleshoot connection issues.
