Hello everyone :)

I have a linksys router model:befsr41 and when i open emule and i connect to the servers, first of all i get really low speeds and a low id plus the power light keeps turning on and off every 1 minute or so it does like a restart and the computer loses intetnet for a second and then connects back on again.Though i have used the port fowarding option on my linsys it still has the same problems when emule is opened and connected.This dosent happen when i just do the rountinely internet surfing.

I have read in other sites that linksys routers tend to do this when use with programs like emule or when dowloading torrens.

The symptom you described (the router power LED cycling and a momentary Internet drop when eMule is active) points to the device actually rebooting rather than just losing a NAT mapping. Since 's suggestions (port mapping and connection tweaks) were already tried, the next steps are targeted diagnostics to find whether this is overload, firmware instability, or a hardware/power fault.

Run a continuous ping to the router and to a public IP while reproducing the problem so you can timestamp exactly when the failure happens. Example (Windows):

ping -t 192.168.1.1

Watch the router admin page for uptime and connection counts just before the drop. If the router supports syslog, send logs to a PC to capture messages immediately before a reboot. Swap the router power adapter (or test its output with a multimeter) — failing adapters can reboot hardware under burst load. Also test by connecting the PC directly to the modem and running eMule briefly; if the modem/ISP stays stable, the router is the likely culprit.

Configuration and mitigation steps to try next: gradually reduce eMule's aggressiveness (upload cap at a safe fraction of your line, fewer simultaneous peers and fewer concurrent connection attempts), disable UPnP so ports aren't constantly remapped, and avoid huge bursts of connections. These reduce stress on NAT/connection tracking. If you still see reboots despite conservative settings and a healthy power adapter, the router firmware or hardware is likely at fault.

If diagnostics point to the router (logs show crashes, uptime resets despite low load, or an adapter swap does not help), replacement is the most reliable fix. For heavy P2P use look at devices or setups designed for high concurrent connections (modern routers with updated firmwares or a small pfSense/OPNsense box). Changing MTU is unlikely to stop an actual reboot — MTU affects fragmentation and throughput, not device stability. Checklist: swap power, enable logging, continuous ping, test direct-to-modem, lower eMule intensity, then replace hardware if reboots persist.

if you want to use a router with emule you need to do two things:
1. define the emule ports in the router, in order to get the high-id and better speeds
2. in emule define the concurrent connections to less than 256 ( I just set it to 200) because most routers just die when the connection limit is set to higher numbers.

if that doesn't help, try to upgrade the routers' firmware to the latest version

Dima thx for the response, I did everything you suggested but the
router keeps disconnecting every 1 minute or so.Do you think that maybe
if I change the MTU on the router that it would help? The MTU is set to
default 1500....

I searched a couple of days ago on Emule support forums and I found a person with the same problem and he had a Linsys router just an older version.Could it be that Linsys routers aren't made for P2P programs.

http://forum.emule-project.net/lofiversion/index.php/f24-150.html

Could anyone tell me of a good router that they havent had problems with p2p networks. A fast and reliable router...

as for MTU, you could set the MTU to 1492 or even 1456. 1500 is good for ethernet, but in the WWW MTU might be different.

now, are you gettinh hi-id now, that you've set the ports?
