Based on the provided website text, here are some troubleshooting steps you can perform for slow internet speed with Cisco AnyConnect VPN:
1. Check the ASA configuration: Review the configuration file of the ASA to ensure there are no limitations or traffic shaping policies applied that could restrict the VPN speed.
2. Evaluate the VPN client settings: Check the AnyConnect client settings to ensure there are no limitations set on the client side that could limit the internet speed.
3. Confirm the internet connection speed: Perform a speed test on the local internet connection to verify the actual available bandwidth before connecting to the AnyConnect VPN.
4. Test on different networks: Try connecting to the AnyConnect VPN from different networks, such as a different Wi-Fi network or a cellular network, to determine if the issue is specific to the network being used.
5. Verify VPN concentrator resources: Check the resources on the VPN concentrator (in this case, the ASA 5505) to ensure it is not overloaded. High CPU or memory utilization can cause slow VPN speeds.
6. Review VPN tunnel encryption settings: Consider adjusting the encryption settings if they are set to a very high level, as it can potentially impact the VPN speed.
7. Update AnyConnect client: Ensure that the AnyConnect client is up to date. Older client versions may have compatibility issues or performance limitations.
8. Contact Cisco Support: If the troubleshooting steps above don't resolve the issue, reach out to Cisco Support for assistance. Provide them with the configuration file, network details, and any additional information gathered during the troubleshooting process for a more in-depth analysis.
Remember that these troubleshooting steps are general recommendations, and the root cause of slow internet speed with AnyConnect VPN can vary depending on the specific environment and configuration.
