to fix them<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><\/p>\n<p>If your network is acting up, start by focusing on symptoms. Does the problem affect one device or many? Is it wired, wireless, or both? Below I list common problems, how to identify them, and step-by-step fixes you can try now.<\/p>\n<p><\/p>\n<h3><span class=\"ez-toc-section\" id=\"No_internet_or_%E2%80%9Climited_connectivity%E2%80%9D\"><\/span>No internet or &#8220;limited connectivity&#8221;<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><\/p>\n<p>Symptoms: you can&#8217;t browse, but device shows connected; other devices may work fine.<\/p>\n<p><\/p>\n<ul><\/p>\n<li>Check physical connections: power, Ethernet cables, modem and router LEDs.<\/li>\n<p><\/p>\n<li>Reboot modem and router: power off 30 seconds, then power on modem first, then router.<\/li>\n<p><\/p>\n<li>Test another device or use a wired connection to isolate the issue.<\/li>\n<p><\/p>\n<li>Ping your router (usually 192.168.1.1 or 192.168.0.1). If ping fails, local network problem; if ping works but internet doesn&#8217;t, contact ISP.<\/li>\n<p><\/p>\n<li>Confirm IP configuration: run ipconfig (Windows) or ifconfig\/ip addr (<a href=\"https:\/\/www.hostinger.com\/tutorials\/linux-commands\" target=\"_blank\" rel=\"noopener\">linux<\/a>\/macOS). Look for valid IP, subnet, gateway.<\/li>\n<p>\n  <\/ul>\n<p><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Slow_network_performance\"><\/span>Slow network performance<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><\/p>\n<p>Symptoms: pages load slowly, downloads are sluggish, streaming buffers.<\/p>\n<p><\/p>\n<ul><\/p>\n<li>Run a speed test from a wired device to compare to your plan. If speeds match the plan, the issue is likely Wi\u2011Fi or device-specific.<\/li>\n<p><\/p>\n<li>Check for heavy users or background downloads (large uploads, cloud backups, P2P clients).<\/li>\n<p><\/p>\n<li>On Wi\u2011Fi, move closer to the access point or switch to 5 GHz if supported.<\/li>\n<p><\/p>\n<li>Update router firmware and client network drivers.<\/li>\n<p><\/p>\n<li>Enable QoS to prioritize critical traffic (VoIP, video conferencing) if router supports it.<\/li>\n<p>\n  <\/ul>\n<p><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Intermittent_connectivity\"><\/span>Intermittent connectivity<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><\/p>\n<p>Symptoms: connection drops randomly or reconnects on its own.<\/p>\n<p><\/p>\n<ul><\/p>\n<li>Check cables and connectors for damage; replace suspect Ethernet cables (use CAT5e\/CAT6).<\/li>\n<p><\/p>\n<li>On wired networks, check switch\/router port statistics for errors or collisions.<\/li>\n<p><\/p>\n<li>Disable Wi\u2011Fi power saving on laptops and update wireless drivers.<\/li>\n<p><\/p>\n<li>Look for interference: other radios, microwaves, neighboring Wi\u2011Fi channels. Change channel or band.<\/li>\n<p><\/p>\n<li>Test with another access point or cable modem to isolate hardware faults.<\/li>\n<p>\n  <\/ul>\n<p><\/p>\n<h3><span class=\"ez-toc-section\" id=\"High_latency_and_lag\"><\/span>High <a href=\"https:\/\/www.hostinger.com\/tutorials\/what-is-network-latency\" target=\"_blank\" rel=\"noopener\">latency<\/a> and lag<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><\/p>\n<p>Symptoms: games lag, video calls stutter, high ping numbers.<\/p>\n<p><\/p>\n<ul><\/p>\n<li>Use ping and <a href=\"https:\/\/www.hostinger.com\/tutorials\/traceroute-command\" target=\"_blank\" rel=\"noopener\">traceroute<\/a> to find where latency increases. If the spike happens outside your network, it may be ISP-related.<\/li>\n<p><\/p>\n<li>Check for bufferbloat: large upload traffic can cause high latency. Limit upstream speed or enable Smart Queue Management (SQM).<\/li>\n<p><\/p>\n<li>Reduce concurrent high-<a href=\"https:\/\/infinitydomainhosting.com\/kb\/the-importance-of-bandwidth-in-web-hosting-understanding-its-impact-on-website-performance\/\">bandwidth<\/a> tasks during latency-sensitive activities.<\/li>\n<p><\/p>\n<li>Consider a wired connection for latency-critical devices.<\/li>\n<p>\n  <\/ul>\n<p><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Packet_loss\"><\/span>Packet loss<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><\/p>\n<p>Symptoms: slow, choppy connections; failed file transfers; VoIP artifacts.<\/p>\n<p><\/p>\n<ul><\/p>\n<li>Ping a stable IP with a large packet count (ping -n 100 or ping -c 100) to see loss percentage.<\/li>\n<p><\/p>\n<li><a href=\"https:\/\/support.hostinger.com\/en\/articles\/2152545-how-to-inspect-website-elements-in-your-browser\" target=\"_blank\" rel=\"noopener\">inspect<\/a> cabling and switch\/router ports for errors.
