Hi , i'm just a home user and bought a new CRS326 for my small office. Before i setting it up in the office , i want to make a trial setup at home.
My previous home setup ( Scheme A) :
modem --> wifi router A (1st floor) --->wifi router B (2nd floor) --> server
From My PC when connect via wire to router A (cat6), i can transfer file to server at 90-100 MBps ( using 1 Gig connection)
Also when my PC connected to either wifi A or B wirelessly , i can connect to internet at 80-90 Mbps ( using speedtest.net). So open like youtube will only take 1-2 seconds.
Now , i'm trying new setup ( Scheme B) :
modem ---> CRS326 on port1 ----> all other port are connected (wired) to all other devices ( wifi router B, server etc)
When setting up the CRS , i remove all config and setup a fresh one. I only did very basic setup , nothing fancy.
I only do :
- add non-admin user - disable admin
- add identity
- add wan ip using dhcp
- add lan ip 192.168.1.1
——添加dns服务器
- add masquerade nat.
That's all, no advanced setting like bandwidth limit etc.
Everything is working - ping/internet etc works, but the problem is : the speed was dropped to 1/10th. The internet speed test now show only 6 Mbps. I normally open youtube under 1 -2 seconds, now it takes more than 1 minutes and only load half of the pages. Very slow response. But only for the internet (wan speed), the lan speed has no impact . When my pc is wired to CRS 326, i can copy to server at the same speed as previous - 90-100 MBps.
If i set everything back to scheme A, everything is back to normal.
What may cause this slowness ? I restarted the router , but no luck. I also suspect the cable , so i try replacing cables, still no luck. I'm loosing idea what else may cause problem ? Does anyone can help ? or any tips to track the source of the problem ?
