Hi All,

Please go easy if any etiquette inadvertently broken. Almost never post on forums and even less on technical issues...Reasonably novice with computer stuff but should hopefully be able to follow instruction at least!

I have just swapped previous Vodafone Home gateway SHG1500 for newer supplied HG659. Rang Vodafone to make sure its set up alright although there was almost nothing to do. Basically a straight swap for the 3 Lan cables i had plugged into old modem (Computer, Sky, Smart TV), and they all seem to be working fine in isolation, as well as the WIFI connection to devices. One curious thing that is happening and cant seem to find anything on the net about is this..

If my torrent client is running (and i mean running at all, even if no bandwidth being used), if i attempt to connect to internet through a browser, the connection times out. Also my android device will have a ? appear next to WIFI signal, and tells me "internet may not be available", and sure enough browser on that will also time out.

The instant i exit the torrent client, internet resumes normal transmission.

Have sought advice from Vodafone help desk who didn't seem to have much of a clue. To isolate the problem i swapped older modem back in, sure enough it works fine, no conflict with client running and browser working. Help desk then suggested it might be the increased security on the new modem, so changed firewall settings on modem (reluctantly) to disabled, as they were already set to low. This did not help either (so have since turned back on).

Iv tried a couple of suggestions for similar issues from torrent forums such as reducing max global connections but to no avail.

I have seen a couple of things on the internet about setting up Static IP as possible solution to similar problems but its all new to me so dont want to look at that unless i know theres a good chance it would fix the problem, and i still cant understand why that would be required when i did not have this problem with older modem.

Any help would be much appreciated thanks

This is not related to your query but if your firmware is not the latest, I recommend updating your modem to the latest firmware as earlier firmware had buggy WiFi. Who knows maybe it'll fix the tormenting issues too?

Save a copy of your configuration file to your computer before applying the upgrade. after the firmware upgrade, upload your configuration file to your modem.

Do all of this with a PC connected with an Ethernet cable to the modem, not over WiFi.

Tried a different torrent client?
Also try reducing its max half open connections.
This used to kill my internet.

My pick would be your torrent client is trying to open an excessive number of connections and killing the router CPU.

this, i believe from reading other threads anything over about 1000 can kill those routers

Keeping in mind my noob-ness, are we talking about 'Max global connections' in torrent client settings? If so, i have already tried reducing this from 200 default to 100 to no avail. If not, could you point me to what i'm looking for?

It seems strange to me that i have a newer modem that is spec'd to handle fibre (not that i have fibre) that would be overcome by something (whether CPU dying or whatever), that was not a problem for my older modem which has got to be several years old now.

Also, strange that the instant i kill the torrent client, internet is immediately available again.

Do you have a "Maximum Half-Open Connections" setting?
That is what used to kill my routers.
Try putting that down to 100 or even 50

Also try reducing "Maximum Connection Attempts per Second" if you have that setting as well

Hi Will have a look tonight. Again, perplexing that a newer modem would have more difficulty than an older one but anyway.

Also, on your previous reply, no, haven't tried new different client yet as i have seed ratios to worry about. Will do if i cant find another fix i guess.

Cheers

Disable DHT and also UTP on the torrent client. They use UDP which some routers seem to have issues with large amounts of. It depends on the nat type in the router, but some make an entry for each IP address that your computer sends out to, quickly filling the nat table up and not timing them out properly.

Does the HG659 have QOS ?, set surfing to highest priority and lower torrents

But get your self a router that can handle a heap of connections

The HG659b is an exceptionally powerful router.

It's not hard to cripple any router out there if you set the number of connections high enough.

Router with Torrent app was probably what I should have said

QoS should sort the issue, prioritise the traffic

Never heard of QOS. Just had a quick google to educate myself then a browse through the different options on the router. Doesn't look like anything there that fits the bill. Thanks anyway.

Which brings me back to routers better suited to torrenting

Hi i have tried this but it hasnt helped. Is there any way to isolate the problem further ie see what nat type is and if table is filling too quickly? Sounds like maybe you are on to something.

Download Deluge and let me know how it goes. I have noticed that client is the best for these sort of situations. Seems to be the easiest to configure too.

What client are you using?

+1 to that. I have never had issues with the 659 and it has performed better than most "High end" consumer routers with throughput. Go find me a router for the same price that can handle a gbp/s fibre connection.
