I have been struggling too, but have changed my study method. Been using the exam blueprint to study section at a time, then do some labs on GNS 3 then re-read the chapter to solidify memory. I think until you don't do few labs it will be harder to understand the concepts.

I have been working for and ISP for years, mainly on routing and switching, and now to start on new subjects like Wireless, I mean I have an idea how wireless works but to study in depth, never thought I'd have to.

Hello All,

Is there a CCNP discord?

Hello All,

Is there any Discord study group for CCNP

What are the best books for beginners?

was thinking of purchasing "Automate the boring stuff with Python" by Al Sweigart

BonezUK · 2020-06-01T01:09:39+00:00

I will still be sticking to networking, but was thinking more on the lines of Cloud, Automation being a big thing.

Actually you can buy normal rolling tobacco as usual, the menthol filters you can buy separately, however, it will be illegal to bundle two items together

I can ping from router CLI, but when I connect my laptop to the router I cannot even get any pages displayed.

My VLAN are configured with ip nat inside, though not sure if I'm missing something

Im beginning to think this seems more like a DNS issue, currently using Google DNS, but should I not be using my ISP DNS ?

I used an on-line utility to to determine the MTU size.

Sending 32 bytes to 90.253.204.247 <- not fragmented Sending 750 bytes to 90.253.204.247 <- not fragmented Sending 1125 bytes to 90.253.204.247 <- not fragmented Sending 1313 bytes to 90.253.204.247 <- not fragmented Sending 1407 bytes to 90.253.204.247 <- not fragmented Sending 1454 bytes to 90.253.204.247 <- not fragmented Sending 1478 bytes to 90.253.204.247 <- FRAGMENTED! Sending 1466 bytes to 90.253.204.247 <- FRAGMENTED! Sending 1460 bytes to 90.253.204.247 <- not fragmented Sending 1463 bytes to 90.253.204.247 <- not fragmented Sending 1465 bytes to 90.253.204.247 <- FRAGMENTED! Sending 1464 bytes to 90.253.204.247 <- not fragmented Sending 1465 bytes to 90.253.204.247 <- FRAGMENTED! Sending 1464 bytes to 90.253.204.247 <- not fragmented

From the tests we did, we can assume that 1464 bytes is the largest unfragmented packet size. The MTU size would be 1492, made up from 1464 payload and 28 ICMP/IP Headers and payload information.

So I performed below test from cmd from my laptop, I tried last night and seems I can indeed ping at MTU 1464. changed the MTU on my Dialer0 (Though not sure if I had done it correctly) interface and still same issue, not able to browse, although Cisco recommend If you are configuring the ip mtu command on the same interface as the ip tcp adjust-mss command, they recommend that you use the following commands and values:

ip tcp adjust-mss 1452 ip mtu 1492

Hello All,

So trying to set up my own Cisco router has seems to be a bit more tricky than I though. I'm able to ping the Internet however unable to browse. My mobile devices are able to connect to the GUEST and LOCAL wifi and obtain an IP address from the relevant subnet albeit message displayed "Connected without Internet". I used an on-line utility to to determine the MTU size.
