Product Description

Product Description

Share Your High-Speed Internet Connection Throughout Your Home or Office Think of the EtherFast Cable/DSL Router with 8-Port Switch as a kind of splitter for your Internet connection. Just connect your DSL or Cable Modem to the Router, and all the computers in your home or office can share the Internet -- all at the same time. The built-in 8-port switch lets you attach eight local PCs directly, or daisy-chain out to more hubs and switches as your network grows. Once your computers are connected to the Internet through the Router, they can communicate with each other too, sharing resources and files. All your computers can print on a shared printer connected anywhere in the building. And you can share all kinds of files between computers -- music, digital pictures, and other documents. Keep all your digital music on one computer, and listen to it anywhere in the house. Organize all of your digital pictures in one place, to simplify finding the ones you want, and ease backup to CD-R. Play head-to-head computer games within the household, or against Internet opponents.

A simple and inexpensive way to share your one IP address over your entire network, the Linksys EtherFast cable/DSL router connects up to 253 PCs to a high-speed broadband Internet connection or to a Fast Ethernet or Ethernet backbone. Configurable as a DHCP server or client, the EtherFast cable/DSL router acts as the only externally recognized Internet gateway on your local area network (LAN). The router can be configured via SNMP to filter internal users' access to the Internet and serve as an Internet firewall against intruders.

The router features advanced functions such as dynamic and static port routing, DMZ hosting, filtering, forwarding, and quality-of-service capabilities. All of these functions can be easily configured through any networked computer's Web browser.

The Linksys BEFSR81 router comes with a one-year limited warranty.

Due to the increasing size of my home network, I decided toupgrade to the 8 port BEFSR81 from the 4 port BEFSR41. The two areidentical in size. A Cable/DSL router is a MUST HAVE for those whowish to share a broadband connection. 99 percent of DSL providersutilize what is known as Point-to-Point Protocol over Ethernet(PPoE). This works just like a normal dial up connection where youhave a username and a password. Normally, this PPoE is done viasoftware installed on your computer. This has many limitations. First,the host computer must always be on for others to utilze aconnection. In that sense, each computer is not independent of theother.
The Linksys has PPoE software built into it. Each computerplugged into the unit can access the internet independently of eachother. Better yet, you never have to see a username/password screenwhen connecting to the internet.
In addition to allowing one toshare a connection, the Linksys also acts as a hardward firewallpreventing hackers from accessing your computers. A must have! Youcannot be secure enough these days!
The unit is easy enough to useNovice to expert. While they're are many advanced features, it is notimperative to set or configure them. The html based interface of theunit is extremely intuitive and easy to figure out. The unit itselfleaves a very small footprint.
The linksys supports DMZ which isknown as a demilitarized zone. It basically allows one local user tobe exposed to outsiders. It is used for such tasks asvideoconferencing and internet gaming where constant two waycommunication is essential. In addition Quality of Service (QoS) isonly offered on this 8 port model. It allows you to prioritizeinternet tasks such as http, ftp, telnet, etc.... Not really thatimportant unless you have many users on at once.

Verified Purchase
A few years ago, I personally went to the trouble of wiring my house for a computer network figuring a wired network would be more reliable than a wireless one. I started with a Linksys BEFSR41 router with 4 ports, and after some initial tweaking, this router worked well for about three years needing only an occasional "reset" to correct any problems. Recently, severe slowdown set in, and no amount of resetting would help so I purchased this BEFSR81. This 8-port router was my choice because I wanted to expand the network to 5 locations. Besides, in today's market, there aren't that many WIRED routers to choose from - WIRELESS seems to rule the marketplace.
Anyway, upon installation, the BEFSR81 experienced severe slowdown just like its predecessor. I checked with my cable internet provider (Comcast), and their signal was coming through okay. I detached the router and ran just one computer directly to the cable modem. It worked great, so the router was definitely the source of the problem.
I contacted Linksys Customer Support and was instructed to download and install some firmware which should correct the problem. No improvement. Back to Customer Support where the usual "power cycle" (unplug router and modem, then re-plug them both in) was suggested, tried, and failed. Finally, the support tech led me through the steps to change the MTU (?) from 1500 to 1490. STILL no improvement. After this the tech said "Wait 24 hours. If the problem persists, call back." Needless to say, I was not confident, but I was too frustrated to bother trying anything else.
24 hours later - no change. BUT, 48 hours after THAT, with no additional intervention from me, everything was great!?! It's been fine for the past 6 weeks now, but don't ask me why.
I'm sorry if this review makes you feel ambivalent toward this router, but that's exactly how I feel.

I liked the specs on this device so I picked one up today. I was especially looking for the QOS abilities as I often have a download in progress (ftp, scp, etc) and I want to give my web and ssh connections priority so I can do real work while the downloads are in progress.
Set it up, nice interface. Set the QOS to the way I wanted it.
Did some web browsing, file transfers, ssh connections.
Then after about 5 minutes I noticed that ftp's would suddenly 'stop' for 10-15 seconds, then resume (using hash mode so I could see progress). This is a linux to linux xfer.
It got really bad, then my web pages started slowing down. I was using MRTG to plot the traffic flow on graphs since the router does SNMP. Traffic showed an average of 56kbps on a 1.54mbps dsl connecting to servers one hop away!
I rebooted my pc, the dsl modem, the router, my flourescent lights and the the kid next door. (ok, I'm kidding about the lights. And the kid) Still jerky downloads, even when NO other traffic on the link.
After about a half hour of frustration, I put my 'old' SMC Baricade (about 2 years old) back. All the issues disappeared.
Sure wanted the QOS, but getting it meant I lost QOS. I hate to say it but I have had problems with other linksys stuff (56k wireless).
Taking it back to Best Buy, sorry guys you'll have to make Linksys pay...
Cisco Makes great stuff. I hope they can apply some of their abilities to Linksys. I hate to put in a negative review, especially since there (may be) other positive reviews. This is just my experience. Also, I am not an 'average consumer' but someone who has experience with 'real 'Cisco stuff, especially ds3 and gigibit routers. Please Cisco, fix these guys stuff!
