Hi all,

I got this new router TP-LINK MR3020 which I has 3 modes it can run in - 3G (for use with modems), WISP and Access Point. When I log in to the router for the first time (through the default IP address of the router), everything goes fine. But as soon as I complete the quick Setup (set SSID and security) and the router reboots, the connection is lost (expected) and when it reconnects, it either does not connect or has limited connection.

The internet works well with the direct wired connection. But through the wireless connection (if at all established), it says the proxy server is refusing connections.

On pinging the router (when the connection does get established),

PING 192.168.0.154 (192.168.0.154) 56(84) bytes of data.
From 192.168.0.101 icmp_seq=1 Destination Host Unreachable

I tried using the router on a friend's laptop (same model, only difference is in the OS; I run Windows 8 and Ubuntu and he uses Windows 7) and it worked ridiculously easily.

Please help! I need the wifi for all my devices. Thanks!

Notes and a focused checklist for (building on ’s firewall idea and ignoring ’s reinstall-OS suggestion):

The symptoms (works wired, wireless shows limited/proxy-refused, and a failed ping) most often mean a client-side networking issue (DHCP/proxy/firewall/driver or a router mode mismatch), not a defective MR3020—especially since it worked on another laptop. The first goal is to determine whether the client actually has a usable IP/gateway and whether a proxy is active.

Quick diagnostic commands (run in the failing OS and replace <router_IP> and <iface> with the actual values):

Windows:

ipconfig /all
ping <router_IP>
ipconfig /release
ipconfig /renew
netsh winsock reset
netsh int ip reset
netsh winhttp show proxy

Linux (Ubuntu):

ip addr show
route -n
ping <router_IP>
sudo dhclient -v <iface>   # replace <iface> from ip addr output
dmesg | grep -i wlan

Immediate tests to isolate the problem

  • Check IPv4 address: if it’s 169.254.x.x or missing gateway, DHCP failed. Try a temporary static IPv4 on the same subnet (use a free address) and ping the router. If static works, the router’s DHCP or the client’s DHCP client is the culprit.
  • Check browser/system proxy: browser-level proxies (Firefox) or system proxies (Control Panel → Internet Options → Connections → LAN settings on Windows; Chrome uses system proxy) will show the “proxy server is refusing connections” error even with good Wi‑Fi.
  • Temporarily disable third‑party security suites and Windows firewall for testing (briefly).
  • Wireless specifics: set the MR3020 to Access Point mode (not WISP) for a simple AP test; use WPA2‑PSK (AES) only; try a legacy 20MHz channel if the client’s adapter is old. Update wireless drivers on the problematic machine.
  • If nothing helps, restore the MR3020 to factory defaults from its web UI (or use the reset per manual), reconfigure in AP mode, and test again. Back up settings first.

Summary: follow the command checklist above, verify proxy and DHCP first, then test with a static IP. If a static IP can reach the router, focus on DHCP/proxy/firewall on the client; if it cannot, focus on wireless driver/settings or router mode.

I havent had much time with Windows 8 yet, so my first thought is for you to look at the Windows firewall settings.

Normally, the Destination Host Unreachable (pre Vista) meant that there was no route information in the computer's local routing table. Since Vista, this error message simple means that no ICMP packets returned from the target.

Since you were able to get this to work with another OS, I would look at the Win 8 firewall settings to make sure that you are not blocking outbound and/or inbound ICMP packets.

Is this computer a dual boot system? Where you able to PING it from Ubuntu?

ok! very simple. uninstall window 8 and install window 7.
