title: OpenWRT: Cant install packages - memory issue
body: <p>I switched from default firmware to OpenWrt for my: <strong>TP-Link TL-WR1043N/ND v1</strong> and have the problem that I am <strong>not able to install any new packages</strong>.</p>
  
  <p><strong>What I did:</strong></p>
  
  <ul>
  <li>Flash OpenWrt</li>
  <li>Installed Luci (no problem there)</li>
  </ul>
  
  <p>And than when I try to install anything else I get:</p>
  
  <pre><code>Collected errors:
  * xsystem: wget: vfork: Out of memory.
   * opkg_download: Failed to download http://downloads.openwrt.org/snapshots/trunk/ar71xx/generic/packages/luci/luci-app-wshaper_git-15.338.68695-3bae3c7-1_all.ipk, wget returned -1.
   * opkg_install_pkg: Failed to download luci-app-wshaper. Perhaps you need to run 'opkg update'?
   * opkg_install_cmd: Cannot install package luci-app-wshaper.
  </code></pre>
  
  <p>The important thing seems to be : <strong>* xsystem: wget: vfork: Out of memory.</strong> And yep I did try reboot and 'update' several times.</p>
  
  <p><strong>But under Luci -> Software I can see:</strong></p>

  <p>Please does anyone have any idea what could cause the issue? I know the solution could be using an external USB but I want to aviod this at all costs + I cannot imagine that this router would have space just for luci :)</p>
