YEP, Netinstall with PXE boot fixed it!!! Many thanks - that's saved me around £100... Also, I upgraded an old RB133C from 5.8 to 5.26 with netinstall and PXE boot - it would not take the .npk file by simply copying it to the board in 'files' and rebooting, but the PXE boot wrote the new 5.26 to the...

billr

Thanks, I will try this...

I am not very hopeful, however - you will see the failed boot in my first post, and the fact the system halts when trying to load the program.

However, the action of powering on and holding the reset key may work and enable me to get the OS into the NAND.

Many thanks!

billr

Any thoughts please? Firstly, how to get Router-OS onto a CF card... Secondly, how to possibly recover from what looks like a corrupt OS in the onboard NAND storage. I can see from the boot menu I can format the NAND but if I do that, how the heck do i get a new copy of the OS onto the NAND (and I l...

Hi there, I know it's an old board but I would like to use it... I have RB 532 which won't boot. I can use terraterm to RS232 into the console and can see the Routerboot 2.18 messages... a) Boot loader is 2.18. I believe I tried to upgrade it to OS 5.17 and after that it would not boot. I thought I ...

MLPPP on adsl lines is very dodgy, even great adsl lines... I tried it on aDSL max lines and on two 8 meg lines got only a little increase in speed. 10 megs or so. MLPPP was designed i believe for isdn. The least lack of symmetry between the lines can really mess up the speed. I took the same lines ...

billr

A quick reply in haste but you have given me some interesting things to consider... I realise about the upload but I have to admit I have not been monitoring as closely as maybe I should.. One other comment I would appreciate is (if you don't mind saying) the backhaul you have, the number of custome...

billr

Hi again, I would really appreciate comments from MT people on the number of connections, cpu speed and memory, and software version - and if any or all of these could be limiting my fairly fast 32 meg backhaul connections...

Or do I need to look elsewhere?

Cheers, Bill

billr

The old version does not seem to have any way I can monitor how much all the prerouting I am doing is loading the system? The only trouble in testing is it is all or nothing - I have to replace the old server with the new (would also involve taking the whole network offline for the duration of the s...

Hi there, I would apprecate some general advice. I run a small WirelessISP with my main edge router to the internet a PC with 750 MB ram, 2 gig processor and a 64 MB flash card.

billr

Thanks - that is what I thought...

However one or two of the new P2P blocking features could be useful - but not at the expense of crashing my main router..

I would really like someone like Normis to comment please....

Thanks..

But as I said it's a PC - x86..

Hi all, As title, I have 2.9.46 on my main outside facing PC router. It is working fine and (although I use up to 5.16 on CPE and some of my test / personal routers) I do not need any of the new features.. The license would allow upgrade to V 5 QUESTIONS: a) is it *safe* to upgrade?? b) if I decide ...

As title... I have been running MT for ages (well several years..) and was glad to discover to MLPPP was supported. However as title.... poor performance. I am using an x-86 box with a fairly powerful (for MT) CPU - a micro-ATX board etc. CPU power is not an issue. I have two 8meg / 800k aDSL lines ...

billr

Actually in the case of near line of sight, through trees - as they are predominantly vertical .... you often find radio will sneak thru better using vertical polarization....

But it can be marginal, and it's usually a case of trial and error..

This post comes to you via a wireless link to my (mini-itx) MT router THEN VIA a Huawei E180... IT works!! The trick - ALL MY SIMS HAVE A PIN ... I put one on as a matter of course. However this does not seem to be supported.. Remove the pin and eh VOILA!! It is only slow as it's GPRS. Cheers, Bill

PAH..

Log says:

I can't seem to get no init string sent.. the 'modem init' page shows blank but the modem apparently still thinks it is getting an init string

billr

Many thanks....

They look similar to the ones I used .. except for the MSCHAP authorization.

Come to think of it, that could be the problem at the issue was not getting authorized.
Will try to let you know if I am successful..

Cheers, Bill

HELP please - can anyone give examples of Huawei Dongles that worked please?

Many thanks.

Hi all, It's great the MT supports dongles .... but it is not easy!! I have Huawei E160, E169 and E180 - all unlocked. And sims for UK 3 network, T-Mobile and others. All work fine on laptops.. However on X-86 - version 4.6 (latest I think) I have not had any luck.. a) The USB dongles ARE recognized...

Actually I don't want to load balance thru the WEB proxy, I just want to AVOID the damn thing depending on the source IP (ie 192.168.173.0/24)

Hi, I am using 2.9.46 at the moment (I don't yet dare to upgrade!) However we have now two aDSL lines coming into our MT router. We would like to implement not actually load sharing, but direct traffic depending on its source ip (ie 192.168.173.0/24) to a particular interface. Just using prerouting ...

Hi, It seems to have settled down and to be working fine.. I think the CF may have been dodgy. I tried it with an IBM Microdrive (!!) 340 MB (an old one) and it worked first time.

billr

Hmmm..
Thanks again.

However, all I have are X86-PC systems running 2.9.46 or .49 RouterOS.
There - is it safe to simply FTP the .npk file to them for upgrade?

I am *not* talking about routerboards or WRAP or anything similar.

Cheers again.

billr

Hi and THANKS !

I have several systems with 2.9.46 and 2.9.49, and nothing lower.
So from what you say, it looks like I can go ahead.

Much appreciated..

Cheers, Bill.

billr

Many views but no comments..

Please people, could someone comment and hopefully confirm I can upgrade (relatively) painlessly..

Many thanks, Bill

billr

Sorry if this has already been asked, (I am sure it has) but I can't find a definitive answer.. I was around in the 2.8 days and upgraded to 2.9 with some pain (not all the rules carried across) - but that was around the time we were starting up as a WisP and we didn't have too many rules to carry a...

billr

But (sorry) I should add, we are considering upgrading the leased line and doing things the way you surmised

)

billr

Actually to clarify things we have a 'slow' leased line and fast bonded adsl and use the bonded adsl for the bulk of our traffic.. It may seem the wrong way round but there are reasons.. We failover to the leased line when (note I say when) the adsl falls over - which it does once in a while.. Cheer...

billr

Well that sounds **good**

We are seriously considering upgrading to some professional server grade kit (not just stuff that fell of the back of a lorry ..)

The only (ha!) problem is dealing with the VLANS.

Thanks for the advice.

billr

Hmmm.. Thanks for the info.. Our 'front end' ie public interface is a leased line and a bonded adsl pair of lines. Neither of these use VLANS. However we have a number of VLANS on our network. Am I right in assuming we can use VLANS therefore inside our network? uk52rob who is my partner in crime ma...

billr

Anyone comment please?

ALSO - can someone comment to my question, that if we are running two mirrored MT servers then we need two licences? Or not?

Cheers, Bill

billr

I wondered if that was an answer.

Many thanks.

Cheers, Bill

billr

I have a further question if we operate two mirrored servers, one as master and one as backup.

I would assume that as each server is running MT, we would need a licence for EACH server that we ran?
So if we had two servers, a master and a backup, this is obviously TWO licences?

Many thanks again..

billr

Thanks for this - but unfortunately we have a number of VLANS.

The VRRP as implimented in MT says it does not support VLANS.
Is there a work around for this?

Cheers, Bill

billr

Maybe a strange question, but we need to improve our Mikrotik system. Is it possible to run MT on (say) a dual blade system with failover - so each is mirrored, and if one fails the other takes over? Or is there another configuration option - dual servers with failover. Our problem is the MT server ...

billr

Ok .. one final question.

Given the card

a) has four 100 MBits/s ports
b) routes different IPs to the correct address ?

WHAT is the extra advantage with a card with 4 NICs, which costs more?

Cheers again.

billr

Hmmm, thanks again. But as I said earlier, I am using this card at low speeds (adsl backhaul, WLan backhaul) - up to 20 or 30 MBits/s max.. The only concern I have is one 'ethernet' port is shown in my MT box - but I want to be sure it routes to the correct interface.. Ie I assign 192.168.2.10 and 1...

billr

Ah, ok, as I said I wondered what the disadvantage was... I am using 2, maybe 3 of the interfaces and the speed on each interface will certainly not exceed 1/3 of 100 Mbits/s - as they are connected to either dsl or WiFi backhaul links. DSL at a maximum of 7 MBits/s, and WiFi at 14 MBits/s. So priov...

billr

Ok, thanks, I thought that might just be the case. The picture you have very kindly included is very similar to my card. The RB 44 has 4 nic chips on it so shows up as 4 interfaces, yes? But - can you confirm (as my routing knowledge is not brilliant) I am correct when I say I can assign 4 IPs (or m...

billr

Ok, I freely admit routing is not my strong point (I'm the radio guy..) I have bought a (cheap) 4-port Ethernet Router Card A-3905 based on the Realtek 8139 chip. It is recognised fine by MT 2.9.44 and works. When I put it in my MT box the Reatek 8139 driver is loaded. But what confuses me totally i...

Hi all, A LONG while ago (6-8 months) when the licence policy changed and Netinstall was written, I posted I would eventually try and upgrade my x86 2.9.26 system using Netinstall.... Well I have finally bitten the bullet and done it, to 2.9.40. I was worried I would lose both my licence, key and co...

billr

Fair enuf .... when I try I will hope to post the results !!

Cheers again..

billr

Thanks for all this.

Maybe someone will read this to satisfy themselves it is a good method to upgrade.

Cheers !

billr

You were too quick for me, as you will see above I have run the install on a fresh CF card - and it works fine for me, but I assume it reads the CF card and checks for : a) formatting (the program formatted to FAT and hung, but when run a second time it worked so the CF ideally needs to be formatted...

billr

Hi, I have run MT for well over a year but am puzzled about the new Netinstall upgrade method. I have licences for 2.9 so can upgrade to the latest 2.x version (as I write this, 2.9.29). I can't do FTP as the 'licence' has expired but the new policy allows me to upgrade all 2.x versions now. However...

billr

I found a bug. (what's my prize? )

((jonbrewer))

Well don't tell people, they'll ALL want one in their soup....

------------------------------------------------------------------------

SORRY I could not resist it !!

billr

Nevertheless... amps both increase noise and reduce dynamic range.. And usually do not amplify both TX and RX signal. Antennas do not increase noise but give gain to both TX and RX signal. Your quote from literature - ok, it would say they are good as it is trying to sell you an (expensive??) unit !...

billr

With amps all you end up with is extra noise. For a variety of complex .. quantum .. reasons, the S/N ratio goes down and you are worse off. THE best noise free amplifiers are HIGH GAIN antennas .... and of course, these also have the advantage of amplifying both RX and TX signals equally. IE a 20 d...

Sorry for pointing out obvious..

Yes - legal to use in Eu / UK. IT **has** TPC. In the UK we are only required as I understand it - to be ABLE to control the TX power. We can do that on the atheros cards. Set whatever power you want. In UK there is no requirement for 'automatic' power reduction - unlike in some Eu countries I under...

For the record - working very hard !!

billr

Hitek, I can't see how it is noise related.. One link that drops and reconnects is (as I said) a 50 metre or less link, for test and assessment - with -50 dBm or better signal and hence S/N will be at least 40 dB and probably nearer 50 dB. And it is a) on the less used 5.8 GHz band and b) in a very ...

billr

I have just sent **another** supout file for RC 10 showing a link dropout ('no beacons received') about 20 minutes ago.

Sorry I was not quick enough to catch this sooner.

You should have an RC 10 supout file from me @frambroadband.com

I am not sure however if this extends back in time long enough to show a disconnect.

The problem was - the antenna port was not correctly set !!

Hope this is the answer for you!!

billr

These dropouts occurs on:

Test 50 metre link set to 54 MBits/s. Signal level -50 dBm or better - ie S/N at least 40 dB !!!!

Real 1 mile link (signal -72 to -78 dBm) allowed to vary rate.

supout.rif files sent for both rc 2.9 and rc 2.10
Hope this helps you to fix it.

Hi all, I have searched the wireless manuals and this forum and found **some** information on CCQ (connection quality in %). What I would like to know is, what is an acceptable value.
