Why is my Netgear router so Slow ?

Thread Starter 
I have 2 wireless routers, an old 3com one and a Netgear DG834G v3 router.

I would love to use the 3com all the time but it's not compatible with the Wii and the DS. So 6 months ago I got the Netgear, and ever since my net connection has been iffy. My web surfing drops (but MSN, IRC and Downloads still works) which then needs rebooting, the ping is stupidly high, and it's also slower ! The 3com can get just under 4mb download from www.speedtest.net, but the netgear can only manage about 3mb.

Do I have a duff one or are they all the same? What makes it slower than the 3com?

Ok, lots of questions...but will help me, help you out.

What connection type? DSL or Cable? Modem- is it just a modem or one of those modem/routers? What speed is you wireless? B-G? Is you connection PPPOE (do you need to add a user and password?, if so then yes you using PPPOE).

Few things off the top of my head...

If you modem is also a router (if you can pull a ip from it being directly plugged in) then make sure its in BRIDGED MODE. This will only give you a connection and will allow the router to connected to the internet. If you dont do this, then you double NAT'ing and it might cause your connection issues.

If you using 2 wireless routers, then make sure they dont have the same SSID or on the same channel. Check for interference around your wireless routers, maybe move the router from any electrical devices.

What can make them so different in speed? Easy....EMI...B/G mixed mode, both routers running NAT, interference with the other router since they both using the same frequency or channel.

This is just a thought, will try and give you more info if you answer those questions.

Sorry, I should've made it more clear

Both are ADSL wireless router. they are both B&G standard and I use WEP encryption. I actually only connect to my PC with Cat5 directly to the router since it is next to it.

Both router firewalls are on, i haven't touched the security settings, what i don't get is how come the 3com is (not just feel but actually can tell) much quicker at loading a site, downloading a file. The Netgear feels like something is choking it.

could be the differences in firewalls. The 3comm is older? It might also be a problem when both using a firewall. How are you connecting 1 modem to 2 routers? Piggybacked? If so, then i believe you need to turn off NAT on one router. In fact, if you not using the wireless at all on one router, then just turn it off.

One thing you might want to try, if your going wireless, try changing the channels. It could be an interference issue, I have an old Netgear MR814 V2 that I been using since 2001 fine till I moved. In this new house, the speeds wirelessly slowed drastically. I changed the channel to 1 and now I'm back up to full speed, if I change it back to 6 or 11 it starts choking. When changing the channels stick to channels 1, 6, or 11 the other channels are overlap channels.

I have 2 wireless routers, seperate, not using them together, they are both 1 box modem/router/wap solution.

Ok, if you not going wireless...have you turned it off on both routers?

Im still not understanding though, how is the modem connected? To which router, then how is the other router connected?

Or, you have 2 completely different locations, each with 1 PC- Modem - Router ? If thats the case then its known that some locations might be faster cause your closer to a junction point or better wiring. I get about 4-5 megs here at my house...but if i go to a friends house in another town, his is about 3.5-4megs. We both have the exact same service and package (ADSL 6meg)

Oops my post came after this, if he is using a router into a router that will definitely slow things down. If you need more then 4 wired connections, I would suggest a switch as opposed to adding another router.

Edit:
I just reread this, sorry, I think correct me if I am wrong OP, are you talking comparing the 2 routers not actually using them in conjunction.

Indeed, if both his routers are setup to run NAT then its going to slow down even more. On top of that, which router is running DHCP? If both are doing it, then there is going to be a problem there.

Bellsouth gives us this Modem/router when you sign up for the service. If he has something like that, he could be running 3 different firewalls, one on each device.

ok....

Phone line - microfilter - router (which has a modem built in) - PC

All wired ok?

Forget about wireless, it's not an issue here, just on my PC (connected to the router through Cat 5) is slow when using the Netgear.

Nothing changed except the router (which is also the modem as well), i just unplug one and put the other one in, didn't even move the pc, the plugs, the phone socket, nothing else BUT the change in the router.

Thats right, from modem/router to PC...if you going to use another router, then you plug that cat 5 from the modem/router to your internet connection port on the router.

However, if you do this, you need to make sure that the Modem/router is in bridge mode, another thing is you need to make sure its not running its own NAT. If so, you are double NAT'ting which is known to cause problems. It will work, but it will not be a solid connection.

No................. !!!!

The phone line goes into the router since it has the modem BUILT IN ....

am i being confusing here ?

phone line -> router/wap/modem -> pc

You are suggesting putting the phone line -> PC -> router back to -> PC ?

No, i edited it out...i read it wrong.

You have exactly what most people have...you have a Modem/Router from the ISp, then you have another Router (netgear) correct?

If so, re read my post above...it will explain.

Yea in my edit above, I figured out what you where saying sorry took a few posts. 3 Com works great, switch out to Netgear slow....The only thing I can really recommend is to check what version frimware you are using, and check here at Netgears site and see if it is up to date.
