Half speed with wired router connected

[foxterrier]

Just had 10mg installed.
With modem connected direct to PC I get d/l speeds of 9600kbps.
I'm pleased with that!

However, when I put my Belkin wired F5D5230-4 router in place I'm getting d/l speeds of approx 4600kbps.
If I reconnect the modem direct to the PC I'm back to 9600kbps

Any ideas on how to rectify this?

Yep, you probably need a new router, the WAN port on your current one is probably only a 10MBit Half-Duplex, and for general use, including the Overheads of the TCP/IP/etc/blah/blah protocols, 4-6MBit is about right.

Sorry to be really thick, but with the spec listed below that seems to suggest the router will run at full duplex shouldn't I get the full monty??

Hi fox i had that belkin router and i binned it and bought an edimax br6104k and my internet has improved a lot. That belkin router is an old one as i understand it and not very suited for these modern times. I still have problems with the internet dropping out but not sure if thats the routers fault or VM and being a complete networking newbie is not helping. I would say buy a new router and you should see an improvement. If some kind knowledgable person on these forums knows of a guide to fully explain routers, their settings and stuff in nice laymen terms i know i would greatly appreciate it .

I think the bit I have tagged as bold in the quote, above, is the relevant bit - and why you get the slowdown when using the router. You need one with 10/100 on the uplink. I had the same problem with my old Linksys BEFRSR41 router.

Thanx everyone

Linksys WRT54GS_UK here I come.

10Base-T Ethernet (WAN) part of the spec is the issue here on the WAN port this means the router is only capable of a maximum of 10Mbits full duplex.

You need to look out for 100baseTX which is capable of the full 100Mbits - make sure you set the WAN port to the correct speed / duplex though and that it matches on the modem it's self else its all fun and games!

Collisions / Jabber anyone?!

i picked mine up yesterday and am going to flash it to the dd-wrt firmware to see if i can get abetter signal from it
