Hello I am looking for advice on a router that has alot of throughput ability. My router seems to be holding back my speed (direct connection of modem to pc is faster) so I need something better.
Thanks

Well, I think you need to provide more details. What kind of speed are you seeing and waht are you expecting? Are there any other PC's on the router? Is it a wireless router? Are you using a wired\wireless cnx? What make\model router do you have?

To answer your quesion directly no current router will hold you back to a degree that you will know it (unless the router is faulty or misconfigured).

So pls anwer the above questions and we'll try to help.

Do you have a faster than 10 Mb broadband connection. That would be the only reason your router isn't "Capable" of handling your connection. I'd upgrade your firmware if your seeing slower speeds than you get when your directly connected. If you just have a smoking fast connection then look for any router with a 10/100 WAN connection.

I doubt that it is the Router per-se.

Probably the combo of Router/computer MTU is off.

Okay for the router I have several to choose from I have 2 smc baricade 7004br , 3 Buffalo WBR-G54 , 1 ISb pro turbo 800. My connection is setup like this my dsl adapter attaches to a 16 port 10//100 switch from there one cable goes to the router from the router there are 3 cables going out , one goes to my wireless AP ,one goes to my 16 port gigbite switch and the last one goes to my other 16 port 10/100 switch. If you are wondering why the modem goes into the switch it's becuase I have 8 static ip's. Now as for speed I use a couple differant bandwith testers and with all my ruters except for the isb I get 740 up 2.4 to 2.6 down with the isb I get 740 up and 2.78 to 2.9 down and with a straight connection I get about the the same as my ISB but the problem is that all of a sudden my isb seems to want to die random crashes driveing me crazy so it is basically useless and I need something to replace it.

Jack is offering help, listen to him. A normal SOHO router setup up correctly won't have significant speed loss versus a direct connection. If it does, you have issues (which may be a bum router, but not always!)

well I have 5 ruoters and all but one slow down the connection and the one that does not decided to start taking a dump randomly so I am looking to find a replacement and when I do a direct connect speed goes up granted it's only beween 1/2 and a 1/4 meg speed differance but the CO is being upgraded so it might be time to upgrade the speed of my service but yet I also want to get all the speed I pay for currently. My understanding is that most older routers were never designed with the idea of multimeg connections and thus they don't really have the ablity to handle the speed were as the ISB Pro Turbo was desingned to handle a true 8meg and also multiple connections (ie 2x dsl or 1 dsl& 1 cable or whatever), kind of like I have a 3 com 10/100 managed switch with a 8gig backplane so that when all 16ports are busy there in theory will be no collisions so it can truly handle all the bandwith as compared to a 16 port 10//100 hub wich only has a 100meg to share between all 16 ports cuasing a speed drop even with all machines correctly configured if the bandwith is not there it's not there and the only way to fix it is to add extra bandwith so thats what I am looking for is a router with more available bandwith.

As others have mentioned, check the MTU of each computer and or the router. Like PPPoE connections (usually DSL) need 1492 often.

Another thing to check is play with the half vs full duplex setting of the computer.

Most routers an handle anything your modem can dish out. Since something like 99% of all DSL/cable modems has 10 mb network equipment inside they can't go over that. The routing capabilities of the linksys WRT54G for example at something like 25mb-35mb, which is way more than enough to handle almost any consumer internet connection.

I have had an old router before though, a linksys NR041 that could NOT handle my connection. I have a 6 mbit connection and at best I could only get 3.5mbit or so worth through that old router. But you are talking 4 out of 5 routers not handling your connection so I dont think thats the issue.

What speed is your internet supposed to be? 3mbit? 6mbit? 8mbit?

Also start checking with download speed tests at http://www.broadbandreports.com/stest
see what results it gives when you switch routers around. Make sure to run it a few times (a differant location each time) with each router.

If the results are all within a few percent of each other then I'd say everything is fine. If some routers are VERY SLOW compared to the rest than I'd say check the MTU of all the equipment.

yeah thats a great site for testing bandwith and I have already done that with the routers and thats how I came up with the isb pro haveing a greater speed, as far as my connecion it is buisness dsl so no PPPoE is involoved. I used severral differant machines for the testing even 2 differant os's and obviously all tests were done on a wired connection and my speed is only 3.0/768 guarenteed ( buisness guarentees are great)

What kind of switch is connected to the DSL modem? What are the speed and duplex settings on the interfaces of the switch and the router? Have you tried the router straight to the DSL modem?

Are you running servers off of the switch connected to the DSL modem? If so, what kind of firewall do you have in place? Are you double NAT'ing? When you connect from the first swith and test your speeds, what do you get?

As for a replacement, I really can't give too much advice. I have a Linksys router and it works great for me. However, on a business cnx I would think about running something a little more robust (Cisco 2601 perhaps) than a consumer grade router.

If your connection is only 3.0 mbit DSL, I can't see any routers being slower than this. The slowest router I've found was an old old linksys NR041 that was limited to like 3.5 to 4mbit or so.

What kind of switch is connected to the DSL modem? Just an unmanaged dell 16port 10/100 What are the speed and duplex settings on the interfaces of the switch and the router? 10 fullduplex Have you tried the router straight to the DSL modem? yes Are you running servers off of the switch connected to the DSL modem? not currently Are you double NAT'ing? nope When you connect from the first swith and test your speeds, what do you get? 2.8-2.9
