we have a cisco 1900 series router installed in a network and have internet lease line of 10 mbps.Is there any way by which i can limit internet speed to individual user ?.By the help of router or by any other mean.

Short answer: yes — you can enforce per-user limits on a Cisco 1900, but you should pick the right tool for the job (simple policing on the router, or a dedicated bandwidth manager/proxy for many users). asked about a 10 Mbps leased line; 's guest-SSID tip is helpful for isolating clients on consumer APs, but it won't give you precise per-IP throttling on the ISR itself.

Practical approach on the Cisco: use Modular QoS CLI (MQC). Create an ACL per user (or per user-group), match it in a class-map, then place a policer or shaper in a policy-map and apply the policy to the interface. Policing is simple and drops excess packets (cheap on CPU). Shaping is smoother for TCP but is only effective on egress and uses buffering (more complex). Be careful: a lot of per-user policies can hit the 1900's CPU limits — for many users use a dedicated appliance (pfSense, RouterOS, commercial bandwidth managers) or enforce limits at the Wi‑Fi controller/proxy.

Example (adjust names, IPs, rates and interface to your IOS version):

access-list 101 permit ip host 192.168.1.101 any

class-map match-all USER101
 match access-group 101

policy-map LIMIT-USER101
 class USER101
  police 1000000 8000 conform-action transmit exceed-action drop

interface GigabitEthernet0/0
 service-policy output LIMIT-USER101

Notes and cautions: apply the policy direction that matches what you want to limit (egress on WAN to throttle uploads; egress toward the client or WAN ingress for downloads — behavior differs between policing and shaping). Verify with show policy-map interface <if> and show access-lists, and test with iperf or a browser speed test. Start with one reserved DHCP IP or static assignment per user to make ACLs easy, and test thoroughly so you don't accidentally lock out management traffic.

Just limited speed by using the guest network on my spiffy new TPLInk Archer C9 AC1900. Go get its manual and see if it does per user?

Sometimes I wonder why they used that name for the line.
