Help with my ADSL Router

[Fozzie]

Recently my router seems to be randomly disconnecting from the Internet.

Like now I can't log onto my Home PCs and they of course can't return their work. Good job they should have a few days supply but I am sure when I go on holiday that this will happen and they will run out of work.

It's a US Robotics MaxG I think, I'll check when I get home.

Is there lots of traffic when it goes down? I had a rubbish router which would crap out if I had overly aggressive BitTorrent settings, or too many running eOn clients, or a combination of both (or more).

Also, have you checked for a firmware update?

[Fozzie]

I did set a torrent going this morning and it did turn its toes up when I had quite a few e0n clients running.

Any recommendations re an ADSL router replacement?

[alpha]

I'd try tweaking the BitTorrent software configuration first. Solved it for me.

I'm using an old version of uTorrent with the following settings:

Global maximum number of connections: 150
Maximum number of connected peers per torrent: 50
Number of upload slots per torrent: 5

Maximum download speed is unlimited. Maximum upload speed is capped at 25kb/s on my 256k theoretical maximum upstream. As you may already know or have read, it is suggested that you cap your max upload speed to 80% of your theoretical upstream. YMMV.

[em99010pepe]

I had the same issue. I suggest you open port 10204 TCP and UDP ones for eOn on your firewall settings. Also, I use utorrent but I limit my upload to 10 kb/s, a fifth of my upload speed...

Fozzie - hmm stupid router yeah I've noticed a few times mines done that crapped out on me with over agressive downloads and the like it maybe DNS issues what I did was disable the DNS relay option in my router found out my ISP's DNS servers and put them into each PC's network settings it worked still occational lock up but not as many..
Recommendations - Belkin or Netgear although the 834 is good it suffers randomness (some do some don't it's a random, random fault with 'em).

[Scooby Doo]

Is your Line attenuation less than 6db? Is your connection an ADSLMax one?Are you connected with a normal microfilter or a faceplate?

Ive been told the speedtouch 585 V6 is a good one as it is compatible with DMT tool. Also the Netgear DG834G V3 seems to get comsistant good reviews and netgear seem to be good with updating their firmware.

With reference to you current router is this concidetal?

[tnerual]

on my side (it's my job, the router), i will recommend you to find a cisco (second hand cisco are cheap)

here at home, i've made some test with different router (about 10 of them) and emule

if i put 4000 concurent connection on emule (max 200 recommended), the routers crashed after 5 minutes (it's not the computer, the connection was of on the other computers).

with a cisco 837 i was able to go up to 8000 connection without any problem (the computer was not responding anymore, but the router was ok ...) same results with a cisco 827 and a 877

i think that the problem is the saturation of the NAT table.

[PCZ]

I will second the recomendation for the cisco.
You should be able to get an 827 of ebay.
I'd recommend you get the extra memory for it as well.

The cheap SOHO routers don't have enough memory and as tnerual has already mentioned run out of resources with a lot of NAT translations.

Why don't you just stop the P2P ?
There are far better ways to get stuff, try usenet.

[Fozzie]

http://cgi.ebay.co.uk/Cisco-827-827H...QQcmdZViewItem

Alternatively how do you go about using usenet? Any recommendations.

[PCZ]

That'l do yer.
Quite reasonably priced too.

You will find configuring it from the CLI quite hard, we can help with configs so don't worry.
If you can contact the seller make sure it comes with a serial console cable.
Beg for one if you have to.

[PCZ]

Foz
As to usenet.
Perhaps it would be best to discuss somewhere other than this forum.

[gopher_yarrowzoo]

Yeah most routers the mass NAT test is where 90% of them fail - and people wonder why there connections are slow..
Cisco are good, had a look at set up put in for a customer of ours by BT we needed to double check they'd copied across some NAT so we could get remote viewing of cameras work erm well I looked and went "HUH!!!"
this only had 2 VLAN - 1 data, 1 VoiP, I double checked and went to add something to it via it lovely Web Interface - it looks good is all I will say! and...... CRASH! yup I locked it totally, hard rebooted the whole system (didn't need to but thought **** it ) changes I had made didn't appear so knew they'd not went in.
So if you want it to work Foz get the Serial cable for sure it's a MUST, I believe it's a special not like 9pin - 9 pin ; 9 pin to RJ-45 special design.
But it's freaking Bullet proof, as I said before I ignored the DNS forwording on mine as it would lock up daily doing "ordinary" stuff :|, stupid m****rf***ing D-LINK PoS... now I just need to reconfig this new ADSL2 ready Belkin I have so I can rock n roll again...
As for Usenet - agreed elsewhere

[Shish]

That Cisco is a good find and there are some sites offering a copy of recommended basic configs without having to be a Cisco CCNA. The languge and commands in the Cisco setups are relatively common across several router types so once you,re OK with CLI type setups it's not too hard.
As to home types, I always recommend the Netgear types as long as you update the firmware. Sky are a bit of a pain since you must use their supplied router and tho' it's a decent Netgear, part of the firmware is hidden and that stops you updating it. This has lead to a lot of problems as that router had a lockup issue, which Netgear solved, but Sky didn't update their firmware.
Seems like several of the guys have given you pointers to some of the saturation problems and router table overflow that can occur bit I will add a couple more. You can optimise your adsl by getting a real BT data type faceplate with a 2 connect type for phone and integrated ADSL filter as this can give you less attenuation on your connection and you should check for some of the problems the company you use as well as the local exchange can cause. Both may stop you saturating your link, not just in bandwidth but also total connects. Windoze can also give you some bother in this respect as well. I'm on a Max Sky link which should give me up to 16Mb but I only get <8Mb as the exchange I'm on has never been converted for the ADSL2+ speeds. I also gained a couple extra Mb by changing the original BT install to one of their integrated faceplates which cut the original attenuation a fair bit. You may also need to wait for your connection to settle down as some of the equipment will calculate a max connect then a safe connect which is sustainable and a lot of dropouts are caused by weather affecting the noise figures and increasing attenuation as time goes by. Copper or ally wires is also a big sore point with BT across a lot of the country. Different suppliers have different policies so maybe check you're not getting "throttled" if they'll admit it of course . Best of luck mate, ADSL is not the best of technology.

arrived with the console cable as I requested, just need to get this bad boy home and set it up.

Could be tricky as I had it sent to work but I cycle, it would mean a very full backpack.

[Shish]

Unless it's just sandwich box size bag the Cisco should fit easy. It's only a home one.
Setup's not too hard and you can download a readymade setup from 1 of the Cisco fan sites or learn the basic stuff online or at one of the CCBA etc sites. Just Google for either and plenty Cisco guys here I'd figure.
Got the bookssss, teashirt, video, websites, bootcamps....whatever. Think I've still got a disk with the Cisco web tutorlage somewhere tho' may be hard to find as it's bin awhile and there's probably a few more here more up to date than me.

[Fozzie]

but can't access the web gui on 10.10.10.1 nada.

[PCZ]

Now you know why you have a console cable

Hyperterm 9600 8 n 1
No handshaking.

What will be even funnier is if the guy left an old config in there and you don't know the password.

If the config is blank you will get a router> prompt
type enable <enter>
if prompted for password just push enter.

in hyperterminal go to capture text. start a capture file.

on the router
term len 0
sh run

you should get a few pages of text.

Stop the capture.
post the capture file.

[Shish]

Be naughty if he left the access config

[Fozzie]

for some reason.

It doesn't like the virtual-reassembly command a ^ appears under the i.

I can log into the web interface now but it says that it can't access the router even though i can ping etc.

It prompts for a username and password what should be entered here?

Thanks in advance.

[PCZ]

add a username and password
telnet into the router

enable
conf t
username fozzie privilege 15 password makeoneup
ip http authentication local

if you change the following then telnet will also use the username password you entered above

conf t
line vty 0 4
login local

Should have mentioned this earlier but you do need to save the config.
drop out of config mode
cntl z

write memory
short version is wr me

As to the virtual-reassembly command not working.
try this

conf t
int ethernet 0
ip ?
look in the list of commands available, use space bar to scroll should be near the bottom.

Could be it is not a valid command in the IOS you have.
No biggy though as long as the rest of the commands are working.

To see the version of IOS you have
drop out of config mode to run this command
cntl z
sh ver

I've got some time to myself on Weds so will hopefully have it all up and running.
