Hi,
I’m troubleshooting strange issue with slow response web browsing on local network. I’m running a few webservers on few local network devices, some on WiFi, some ethernet. It’s fairly standard setup - RT-AC88U on 384.18, one local subnet, DHCP preset allocated IPv4 addresses. IPv6 off. DNSmasq using
Usually it’s just the first initial HTTP request - sometimes it takes 3-4 seconds before the first page loads up, sometimes the request times out. It usually works well after the initial page loads up with all the other subsequent content onwards. It happens across all the webservers, WiFi or Ethernet (including the router’s webUI), different types (Apache, nginx,...), different operating systems and devices. It doesn’t happen on any external internet websites which load instantly, just the local network.
- At first I thought it’s DNS getting stuck, but all the
- Then I thought DNSmasq might be an issue, but connection to other services like SSH or SMB is instant as well using the local domain names
- Disabling QoS makes no difference
- Nothing strange on ping, everything is fast and no drops.
- Nothing noticeable in the logs
- No router CPU or memory overload
It’s purely web browsing, it’s the same in all the browsers I’ve tried (Safari, Edge, Firefox), from any local network client devices to any local server devices, regardless of using IP address or local domain name. It only happens on the first attempt initially, after longer period of inactivity and then works ok.
What might be wrong?
